Pre-primed aftermarket plastic bumper prep for paint no peeling no flaking make your paint stick 

He said if you want to hate on me, I like that too. Tell your enemies. Loved it. Nice job.

Great information here! I learned the hard way not to trust pre primed plastic bumpers; your video is one of the best, simplest approaches I've seen that can be adapted to a DIYer like me. Thanks!!!

Thank you for this video. I knew there was something I should do to make it easier and what I would have missed would be the adhesion promoter. Nice work and thank you. Help me make my kids car look better as a DIY guy

I thought adhesion promoter was only used on raw plastic ?

Best video out there super simple and not overly complicate it like others thank you

I happy to see all the work that goes into painting a bumper.

I love watching these type videos! Great job

I’m thinking about doing this on my Camry. Good insightful video thx a bunch👍

Good advice on spraying clear. I think I understand the ratios now. Im just dumb but ive got this.

After this video I’m going to give painting my bumper and hold an attempt😂

Nice job

I’m getting ready to spray my bumper tomorrow 😂 1x for anything

You mentioned waiting 10 minutes before spraying the sealer, but what about delay between sealer and base coat, plus the time between base coat and clear coat? And if I end up needing to sand the sealer coat because I'll be using a spraycan primer, how long should I wait before and after sanding the sealer step? Thanks for all your guidance!

My only problem I face is laying primer/sealer down. Everytime I do, I have to sand it down with 600 to get it smooth before I paint. If I paint right after primer without sanding, it comes out super rough! Other than that thank you for the great tips!

You did a nice job..... Great info.

Thanks for sharing.

Thanks for sharing that information great finish

Yes, you definately need to scuff them up good, and clean ALL contaminants off them.

How do you fix a bumper that’s chipping

Thank you!! Hopefully this 50 dollar color code matched aerosol can of paint and separate can of clear coat are enough

Great job Young man!!!

I have a question this is now my second car I’ve had to have panels replaced and painted from an accident. I had them both repaired at caliber collision, not sure if your familiar with them but they get there panels and bumpers from a place called Keystone. Both times I’ve had to have them repainted because of the paint just peeling off. They always want to blame it on keystone. Don’t you think they would know how to prep those parts properly like you do or do you think they’re just taking short cuts. They’re supposed to be professionals and do it right the first time I would think.

I'm about to get a pre primed 350z bumper, I guess I'll take your word for it. Ehat confuses me is what to buy at lowes to make a primer a sealer and im not familiar with mixing. And I only have one paint gun so when I spray sealer ill have to clean it out to paint it black and then clean it again to do clear coat. I was hoping I'd be able to just spray it.

Any advice on getting rid of static from a pre primes bumper?

This is EXACTLY what I was looking for in every detail possible. You don't see much helpful information like this without the guy skipping ten things that leaves us back to point A. But, this video was on point. Please subscribe to this channel and help this guy out the way he's help us out.----from Greedy Grove, Texas 75217.

Is thinning out the primer by 10% to make it a sealer crucial to your claim on the pre-primed bumpers? If so, what are you mixing it with to thin it out? It looks like there were instructions on the UPOL primer can but I currently don't have all the tools for proper measurements. Again, if this is a step you don't recommend skipping to back your claim, then I'll go ahead and do more research to find out exactly what I need to thin it out ...or can i just use primer for this whole step? 😅

I’ve read that you shouldn’t put adhesion promoter over primer, it’s for raw plastic. So if I have one of these pre prime bumpers that says to wet sand with 1000 grit, how do I approach it ?

Thanks for the information, it's appreciated. What sealer could you use if you're rattle canning it in the back yard?

Thanks a lot. One question is how to know the preprimed bumper has a high quality primer ?

Do they sell a sealer in a spray can? I’m doing rain guards, and a spoiler kit. I’m in the scuffing stage. I was going to put adhesion promoter, then use a 2K primer I have in a spray can? Is that sufficient, or do I need some kind of sealer?

My very first bumper never looked this bad. And I did it with the little purple mini harbor freight gun😮...tisk, tisk, tisk...

I ordered a spoiler for my car that comes in a pre-primed black color similar to this I was wondering if it’s okay if I leave it unpainted like that? Only reason I ask is because the matte finish it comes in matches the car’s factory side skirts and diffuser

Can you put links in the description for what the products you used are and where to get them

Thanks for this! Great advice! I'm about to do a bumper myself. The last time I did a bumper, the clear coat looked "orange peely" like yours and even had a small run. I discovered though that it continued to "flow out" seemingly for days after and looked 100% better without having to sand. Have you had the same experience?

Is this problem just on newer ones? I have hundreds of not more out Their many years old and their all holding up fine. Didn’t even peel years later after they wrecked it again. But I also don’t want to risk doing it the old way if this is happening now more then before

BPB Restorations, have you ever had any come backs or problems when applying adhesion promotor to new primed bumpers? I've seen some people say that it could cause adhesion problems, but a few buddies that I know that own bodyshops say they apply it on all plastic bumpers.

Is regular primer considered a sealer or is it different?🙏🏽

What do ypu suggest for guys who haven't got spray guns to apply that sealant ???

Thank you for sharing your knowledge. How long should you wait to sand after the final clear coat?

how many cans of adhesion promoter do you need?

USED BUMPERS OR NEW ONE ARE EASY TO PAINT PRIUS?

Nice job, but I wish you would show gun and adjustments, also normal speed spraying so I can see technique. At least one of the steps

Question… is it worth the extra time and cost to go around the edges into the backside a little when preping to ensure no peeling starts on the back side of the substrate that could turn a corner? Sorry I have terrible OCD and need to know. Thx

Great video. This instructions is to make sure that paint doesn’t peel off. Do I need to do another spray paint of the bumper to make sure that the primed paint get sealed? Or is there no need to do a 3rd and final coating? Thank you.

Does anyone know if this 2k primer sealer is waterproof the way that epoxy sealers are? In other words can it be left outside in the rain for awhile before topcoat?

Does one can of that adhesion promoter do one bumper? How many cans would you get for 2 bumpers? Thanks

You mean surfacer or a sealer!

Do you sand and buff with the bumper on or off the car, good video.

Great video. Thanks Do you use clear coat on standard vehicle paint work, or only pearlescent or metallic?

great job. can you list the items you used. i remember you said primer sealer, adhesion promoter. what other items do i need?

How much $ should I expect to pay for painting my bumper cover M-Tech II 330ci from shop?

nice video man.. just a quick question i need to apply body filler ,do i need to throw some adhesion promoter before the body filler? or just sand the pre.primed new bumper

Can you name the products used ? I currently order one and need to paint it silver

Is the bulldog flexible bumper paint stripper ok to use on polyurethane?

Thank you for this video. The adhesion promoter is applied over the (scuffed up) primer, does it soak through the primer and stick to the plastic?

From Michigan here, have a 96 k1500 that needs rocker panels. How busy are you?

How much paint did you use including the base!

I have to do this very thing thanks to a yote

What is your opinion of the quality of the plastic on aftermarket bumper covers versus OEM bumper covers? I have heard rumors of aftermarket covers being brittle and cracking easy versus OEM thank you.

How long between sealer/primer to base coat and time for clear coat?

Is it the same for pre primed fenders.

This might be a dumb question, but you mention at the beginning of the video that that bumper is pre-primed. It looks just like the bumper cover which came with my Nissan pickup truck when it was new 20 years ago. Does that mean that the bumper cover it came with was just pre-primed, or did Nissan also paint it with a color (AG64) that looks exactly like the pre-prime? I'm asking this because I'm thinking of getting a new pre-primed bumper cover, because mine is faded to oblivion, so I'm wondering if I can just put it on and armor-all it or am I going to need to paint it?

Is car parts a good site to get bumpers?

I have basically that same pre primed bumper. Mine is for a Dodge Dart but looks almost identical. How much should I expect to pay to have someone prime & paint it exactly like you did this one?

Ima be painting in 55-60 degrees weather in the morning that’s the time of my class u think I’ll be good ?

Where is the overspray going

What tip do you use for clear coat?

Does anyone know how long it normally sticks before it starts to peal?

you dont need to wet sand the primer?

Do you recommend something to clean the bumper before scuffing to remove the molding chemicals.

Nice video would this same process apply to painting a plastic boat?

Can i wet sand it with dawn and 600

Do you know any good shops in NJ?

is it a problem if a little plastic primer is applied to the primer already on the bumper?

Can I use filler primer and adhesion promoter?

Will it work to put a primer on top of the Adhesion Promoter?

do need sealer? or can you just use the bulldog thing and than start painting and than 2k clear coat

So I have small are I need fix do I need to prime whole bumper or just area i patch ?

Is it ok to use wax and grease remover on these pre primed bumpers?

What if u sprayed adhesive promoter and then tried base 🤔

I guess the primer on mine was really shitty. Scotch brite, and then the wax and grease remover dissolved the primer.

Very informative but can you show the buffing of the orange peel?

Sealer is primer can i use a gray primer slealer? That sells in autozone

Its a nice video but you left out some important parts.I wanted to see the spraying at regular speed start to finish. Also how you buffed sanded and polished out the orange peel would have been really nice to see seeing as how that produces the finished product.What do you buff with and what compound do you use ? Is spraying too wet or to slow causing the orange peel ?If you use spray cans woulfd you have those problems?if not what is or do you care because you sand the peel out with the 2000 grit sand paper?

What thinner did you use to thin the upol primer

Can i ask why you used Hi build over plastic primer?

What did you use to make it shine like that cheers

👍🏾👍🏾👍🏾

Are yiu supposed to sand it down first

anywhere i can message you so you can respond quicker? i have 0 knowledge of cars and how to fix em alone lol, but i did have to buy bumper covers pre primed, and a fender as well that i plan on painting myself

I'm a day late on this, just painted my new pre primed bumper and the paint slid off on 1 area. Now I gotta order more paint and sand it off. Mother #ucker.

Can I use primer spray can instead of sealant

I thought you have to add "flex additive" to the primer.

Hi how long did you leave the wet in wet primer before base/clear thanks

So this is becoming a mission to get this adhesive promoter product bulldog nor 12316 was at Home Depot or advance auto parts. I am a complete novice as this will be my first attempt to paint a bumper, and I have no clue where to buy these products. Not sure why advanced auto parts will not carry anything similar and they told me to look on Google for body paint shop suppliers in Miami or something like that route when I live an hour away…. Seriously, this is becoming a pain and not worth the time or effort to paint it to save a few bucks when I have to go all the way to Miami to get this adhesive promoter and still not even sure if they have it

Great info but way too drawn out.

went to fast

Would rustoleum filler primer work for this? It’s a water based primer

How long do you wait from the primer and when you put the color on? Thanks
