I picked up a gallon of PPG omni AU primer and 2 things of catalyst.. Didn't pick up the paint as nobody was there yet who could tell me anything. We couldn't decide on a colour, so should I just go for semi-gloss then, or does someone have a paint code? I'm only doing interior, engine bay and undercarriage? Not that I'm going for pure originality here, so if it's ugly or someone has a better idea, let me know.. Also, nobody at this paint store had heard of Picklex, or Ospho or anything. I know people recommend these here, but i can't find anything locally for hte life of me, and I don't have time to order anything online (And duty and what not is a pain) Are they necessary? I'm going to hit the rest of the old DP50 with 80 grit or something on a DA and get the new sheetmetal down to bare metal (Omni can go overtop of the DP50 correct?), is that cool? ALso, I want to use a single stage due to the fact that it's easier for interior, engine bay, undercarriage (But the exterior will be getting bc/cc).. What specific line of paint (is it just called 'Omni'? Dude recommended against mixing a flattener in it (Omni only comes in gloss black) and said he's make me up something else from PPG? Wanted to use what he kept calling "Industrial" paint? What kind of paint am I looking for anyways? Ahh, so many questions.. I'm just doing some garage painting, as I don't need these specific areas perfect.. When would I use a tack cloth and what not? Necessary? OMNI seems to only have a recoat window of 3 days, and I don't have the paint, and won't until at least 24 hours after spraying.. Is it actually ok right up to 3 days? Thanks guys!
