    paint question

    good afternoon

    I have a truck here in satin black.

    owner wants to change colour.ive found what we need 2k Acrylic paint.

    trucks not getting bare metaled,but as we don't know what paints on it now,is there some sort of magical sealer/primer I can use,so the new paint wont fall off

    thanks

    You can get a Barrier Coat, which is supposed to stop new paint reacting with the old and works well in most cases, but if the satin black is Simoniz Tough Black that really doesn't like anything painted over it, so if that's the case it may even react with the barrier coat.

    Yes, you can get 'bar coats' but you might not need it. I'd try a couple of test areas first to see if it holds up.
    2K's go over most things to be fair. It's the thinners that reacts with the previous paint and 2K thinners is quite mild compared to cellulose (which is the strongest).

    2k is 2 paint-1 hardener with a nats of thinner, would be suprised if it reacts, 2k prime it to be safe or bar coat, buzz the black down with 400 disc or finer then test, keep celly off it in all cases if not sure of previous work, either way you got to test a patch as previous post-- before wasting material

    I did wonder whether to do a 2 k epoxy primer over it first as I've made a few new panels in bare metal that need primer .

    you will have no problem over primed panels , but watch the rest, some primers are 4-1 ratio, nothing comes through a few coats of that, if you do break through primer coat , just a dusting over exposed areas, tint your primer depending on colour useing, just kill the black

    Is it not easiest simply just to use a tinted epoxy primer . I've been lead to belive that the process is waterproof and won't suck in water like normal primer does ?

    ive been told the same befor.

    thats probably great if youre car lives inside and is used on dry days.

    this has to live outside all the time.i will get a matching colour with the epoxy primer.once its all preped,its not to much more work to do a top coat

    Epoxy is 'almost' waterproof and it's 100% better than any other primer, but it is definitely not UV stable so no good for a topcoat over time.
