    Default Painting Engine Accessories, Epoxy or Acid Etch?

    I plan on painting all the engine accessories ( alternator, ac compressor, etc.) on my project truck. Obviously trying to scuff these items will be a challenge, which primer do you think would stick better to a poorly prepared surface?

    I like using epoxy primer for most of my priming jobs.

    I was kind of leaning towards the epoxy, it seams to stick real well to almost anything. Thanks Len

    What's on them now and what are they for (eng & vehicle)? Also, what color are you planning to paint them?

    I go with the epoxy too, however, and this is a big however, some epoxies can be thick and these brackets are often of very close tolerances. They bolt on perfectly without a mm of wiggle room then something bolts to them perfectly with zero wiggle room so building up material isn't going to work.

    So check what you can get away with and you may want to send the epoxy down on bolt surfaces like where the alt or what ever bolts to it to reduce the thickness allowing more room to fit the part.

    They are bare aluminum right now, I want them satin black, so I think I'm gonna us SPI black epoxy. I talked to the owner, and their epoxy does not need to be topcoated, so it should work real well..
