As I have had some previous diy experience with bodywork and spraypainting your tips an advice have worked for me,the guide coat bit definitely worked on my m/cycle fuel tank,and the end result was better than all my previous diy work,true,proper prep is required for good end result,kind regards.

@rj3000ii 7 лет назад

Thank you so much for the tips. I'm restoring a 1959 Glastron Fiberglass boat and just primed the hull and wasn't exactly sure what to do next to prep for the finish coat. This video was exactly what I need to see.

@CarAddictGarage 7 лет назад

I am going to start a boat project soon. I would use guide coat and final sand the boat with 400 grit sandpaper. Then you should be ready to paint. You can finish it like a car. You can also use a gel coat, which is a little thicker, but does not have the gloss level as automotive base and clear. This lesson will help you out with the prep process. www.collisionblast.com/paint-prep/ Thanks for watching.

@jamescon55 2 года назад

Leaving it masked off is fine except for when actually using "some" of the extra extra high build Polyester, Epoxy Primers. As the build that it creates will/can leave such a hard/built up edge/line depending on the "masked situation." Plus, applying different stages of primer over the same tape/paper "can" make it a miserable bytch to pull off/unmask. Also? Leaving the used paper can cause LOTTA extra dust/debris that just ends up in your primer being shot, and on some primers? Cause it to "fuzz up" more and ya spend MORE time sanding the stuff vs just using more tape/paper/painters plastic to remask....Just my 2 centavos. Keep a GRINDIN! 👍

@CarAddictGarage 11 лет назад

There are wet sanding and dry sanding methods. Either can be used and both are effective. And you are correct, you want to final sand before painting with 400 to 600 grit sandpaper before painting. Thanks for watching!

@MrElPoderozo1 6 лет назад

Donnie Smith. Hello! I have a question if I may. I am wet sanding 2K primer with 400 and I hit metal on some edges. My question is Do I have to put primer again on that expoused metal and if I do what primer? 2K or epoxy primer? Remember im wet sanding for paint, thanks.👍🇺🇸

@1JoTyler 4 года назад

Great video and i gueas the best advise i could give is to wet the whole car before paint , that will show you any imperfections when looking down the panels. If you are having a hard time getting the lines out use a da file softly but quickly. An older friend helped me with that years ago and the black car came out slick. Keep up the great work!

FINALLY, an instructional video that explains everything I was wanting to know about prepping, priming, blocking and using guide coat!!! Subscribed and thankyou for also considering the people on a budget! I already threw a lot of money out on the rustoleum paint roller technique only to go back to step one again because I either didn't prep right or because crutial information about prepping were left out. Lots of wasted sandpaper, paint and disappointment. I wont be using a spray gun but the techniques you described will help a lot

@CarAddictGarage 8 лет назад

I am glad you found this useful Check out my video page with more prep, prime and block videos. I think this will help you as well. CollisionBlast.com/PaintPrepVideos Thanks for watching.

@ArturB993 8 лет назад

Hi Donny, I asked you a question on another video and would be grateful if could tell me what the main differences are between "sandable" primer and filler primer is? Also is it okay to spot spray areas with bare metal with etch primer and then go over the whole panel with the sandable or surfacer? Thankyou.

@ArturB993 8 лет назад

Also the etch dries a little smooth, worried it won't have enough adhesion.

We did a VW Bug last month. Beautiful. Learning auto body work is so fun, I barely cook anymore. We have nice cars but we are hungry.

@deankay4434 2 года назад

Now 2022, it’s been 11 years since this video aired. The worst blocking issue it almost two fold on the same vehicle. This is my 67 C10 truck. #1 area hard to block is the center of the front hood. It has a peak, reverse crown and convex areas that change from from to rear. I used a contour gauge to form a block from a hood in the package my son bought. Once drawn, 32 grit on die grinder created the front, but it get smaller at the rear. Make a second one and keep going. I was exhausted until I got into the reverse crown that changes to larger toward the rear as you progress down the side, front to rear. Having built a block that fits helps duplicate both sides so close you could not tell. As you mentioned, but black epoxy, covered the a gray high build, let’s you know once you pass thru primer into a sealer into a different color. Thanks.

Thank you for the good video. Restoring my 1971 Lemans Sport convertible, and just cannot afford to pay the 10-15 grand I've been quoted by several for a good street paint presentation. Most shops seem to think concours or nothing. I found a mobile soda blasting company that will do soda blast at my garage. The car is relatively clean of rust with some typical body dings and some wavy panels. I figure if I can do the bodywork and prep, I can save a bundle to then have it professionally painted. Again, thank you.

I just did a F250 for a guy and did a lot of work to it, if it where me the truck wasn't worth the money it took to fix what I fixed

@Tweekend27 9 лет назад

Very informative and easy to follow! I'm starting on my '67 Mustang Fastback soon and am doing the rounds on RU-vid for knowledge. I have a page of notes from your video! I have a question, if you wouldn't mind, when I go to do the roof of the mustang, how do you recommend I attack it? Prime the roof, apply guide coat, then work at it in say quarters, or do complete drivers side then passenger side? I'm worried that doing it in smaller sections won't flow smoothly into the next section and end up with an uneven end job. Thanks :)

@rodskustomsanddetailing8542 11 лет назад

Donnie I love your videos, you provide with so much information that could be the difference between an ok job and a great finish. I have a question though, once you block sand and you end up with low spots, do I just try to level them those spot up with body filler again or glaze putty? or should I simply keep block sanding till everything is leveled?.

@TheEgg185 6 лет назад

Which video does he mention this channel?

@darkwillow57 3 года назад

If you're blocking and you get down to bare metal you can't block that area anymore. Because your sandpaper won't sand the metal but will sand everything around it. So the metal will end up being high if you keep blocking there. Just as I was making this comment I came to the point in the video where he basically said the same thing. Oh well. Thanks for the video it was easy to follow and informative.
