Painting over Powdercoat?

I have some Tomkin rear bumper end caps that I had to have modified (shortened to stop wheel rub). Obviously the cutting/welding work needs to be finished. They were originally powder coated.

Can I rattle-can the ruined finish, or will it have problems adhering to the power coat that still remains? Or, will I need to take all the powder coat off and then re-paint the whole piece?

Thanks in advance!

When I painted my new to me ARB bumper, I just cleaned the powdercoat with soap and water, I didn't rough it up, then took my time and rattle canned it with Duplicolor so it would match the rest of my Jeep. 2 years later I have yet to touch it up, and it still looks really good.

yeah just scuff a bit (red scotch brite pads work nice) clean it (im strange and use rubbing alchohol since its cheap and has never done me wrong) and shoot it - powder coating is just basically paint that goes on dry and is baked on - its really not a whole lot better than some of todays better paints

What he said, and I always use rubbing alchohol when painting anything cleans good.

Alcohol gets rid of the oil that gets on the parts when handling thus causing your finish to orange peel, fish eye, etc....

I though you were about to actually have an informative post, until you said that. Powdercoat > spraybomb, acrylic enamel, and a lot of automotive urethanes i terms of durability and chemical resistance.

Of course it all depends on what type you use. Hybrid, TGIC, polyester, epoxy, there's a whole bunch to suit whatever need you have.


... but you are on the right track with the alcohol bit.
