@@TangoCharlieAlpha me personally would use 320 but if all I had was 150 I wouldn’t worry too much about the scratches showing with 4 coats of primer and 4 coats of paint. I think 320 is what most painters use when they paint aluminum. Probably not extra work for someone though if they just use 150 and nothing else. His legs seem to have came out fine using it. Then again perhaps that’s why he needed 4 coats of primer. I’m not painter. I usually stick with two coats of primer. For most things I paint. Sometimes just one coat depending on the object. If that’s the case then yeah 150 will need to be followed up with less coarse sandpaper. To each their own.
After a partially failed aluminum anodize and dye, this is my next option without having to buy new parts. Thanks for providing the exact info I was looking for. :)
Thanks, I Will try paint an old cassette player Panasonic RQ-SX41 (blue) case. I'm restoring it. Your video and tips just fit on my intentions. Now I need to figure out how reapply the withe letters after finish the paint.
Another awesome vid Bill, have you ever consider doing a video about powder coating small part like compression fitting for copper tubing ? I search all over youtube but haven't see anybody do a video about that.
@@Mnpctech_Giveaway_PC_Mods Thanks you. I put 3 coats of the self etching primer on and bought Sherwin Williams automotive grade single stage paint is what they're calling it.
I did a test on an aluminum pop can with 2 coats of Rustoleum Self Etching Primer and 2 coats of Rustoleum Semi-gloss black and then 2 coats of Semigloss clear. I didn’t sand though before priming. Later that night I did a scratch test with my fingernail. It scratched off to bare metal easily. I let it sit over night and tried another scratch test mid day. Still coming off although a little less easily. This is disheartening. The nature of the piece I need to actually paint has hundreds of ridges on it that would take me a week to sand.

Heelp 🙏🙏🙏 Old lady here. Does anyone know if this can be done with a liquid solution using a sponge applicator? We want to repaint our anodyzed aluminum windows which are all weathered and had the paint falling of in sections. Much appreciated.
Hey quick question... great video first off... i am going to be painting some brushed aluminum paddle shifters for my Camaro; are the scratches from sanding visible once painted? That is my biggest concern at the moment. Reason i ask is because i noticed you used some pretty rough sandpaper. Any help is greatly appreciated and thank you in advanced!
You can see the final finish in the video. If youre concerned this isnt going to meet your expectation, I suggest taking your parts to local Powdercoating Shop, so your parts have a thick and durable finish to last for the life of your Camaro. Have a good one, Miguel!
I’d go with a 400, then step it up to 600 and then 800. Rostoleum makes a variety pack of automotive sandpaper you can find in Walmart that has all the grits you’ll need for like $4. If you still see some after the etching primer, hit it with a coat of regular primer or “high build”. But that’ll likely be unnecessary. I’m always a fan of just the 800, but put the object (assuming it’s xirculr and symmetrical) in a drill and spin the hell out of it. Sand it that way.
Does this add any thickness to the object? I would like to do this to an outer barrel for my airsoft gun but Im worried about running into fitment issues when it cycles. Thanks for your help!
I did something similar. Durability wasn’t up to par, and I’d powdercoat it if I did it again. In any case, I dusted the barrel while assembled with a light color. Let it dry. Then disassembled and masked off the areas where contact would be made with other parts. Simple as that
I'm looking to protect bare aluminum on running boards I just purchased on the underside of them to protect them I guess I just follow the same procedure that you did for the video? I live in an area where it snows a lot and I want to try to make them last longer the company I bought them from says they don't have issues with corrosion but I feel as though if I primer and paint them it would be much better protection then just the bare aluminum that is currently on them on the underside any kind of help or advice you could give me would be greatly appreciated thank you
Hi. My name is Jeff. I have a professional vintage cassette recorder Tascam 122MKIII that has a front panel that is anodized aluminum and has some damage. I can send pics. Are you able to repair this? Thank you
I'm going to try this method on my aluminum paintball barrel. My paintball barrel is black and I want to go white or silver, does it matter what color primer I use?
I would like to paint a brown color of **flat/matte** sheen on top of this self etching primer. I think Rust-oleum only sells glossy sheens. Are there any recommendations what product to use? Can I use any paint? It would be for outdoor use. Thanks!
I got an aluminum bat that i want to paint gold... I' ll not really use it but keep it mainly for decoration... I already bought the Rust-Oleum metallic... Do i need to apply primer?
I know this is a late reply, but no, it doesn't make a difference because there isn't much of a variation between the two grits. If he had said 120 and then 400, then that would make a pretty significant difference.
Hi Bill, wonder if you can help me. I'm getting flat faced machined 6063 parts with a high gloss machined finish - I would like to achieve consistent satin/matte (or the finish you have on your part). I need to do a little deburring on occasion but the toolpaths are so tight that the finish looks great but much too gloss. I tried spraying a matte clear laquer then gloss, then matte but found out the hard way that you need to unlock/rough the surface to allow bonding etc. Is your 6061 finished piece anodised? looks like it's been sanded with about 400-600 grit but its hard to tell from my novice eyes. I'm at the point now where I think I'm going to try some ultra fine scotchbrite pads etc. but any cheap tips would be great, I don't really want to add vapourblasting costs on top at this stage till I sell a few lol
Im wanting to paint my bathroom trim. Will this self etching paint hold up to normal use since its bath trim? Can i use the etch paint outside with just a normal respirator mask....the cheaper ones? I hear Rustoleum makes a self etching paint.
Cheap mask should be OK, as long as you're in well ventilated area. May I ask, Trim for what exactly? If it's something that's going to get wet or collect condensation on the surface, the top coat of paint will eventually chip and peel off over time. This is why retail bathroom fixture and plumbing manufacturers finish their products with a plated surfaces or powder coating.
My advice, take the pieces to local Powder coating outfit if you want a specific color, you can find Powdercoating Services under "Metal Finishing" in your local phone business listings or even check Google.
I did do that. No builds but what I do need to do is mod a way to close off the top of an old corsair c70 case. Because of the way the top is designed there's no real way to get positive pressure going and it fills up with dust.Probably just going to bolt a painted sheet of steel to it.
If you want more positive pressure, how about a couple 140mm fans as intakes on top, with mesh screen filters? You can get c70 top filters here, www.demcifilter.com/c31/VENGEANCE-C70.aspx
Well I've got 140's laying about, I've used the demci filters before but I've never been a fan of the aesthetics. I might do that until I've got the time to do some cutting and painting. It's not as much fun if you buy the solution off the shelf. I actually used your guide to fix the window on the C70. Worked a treat.
