i will tell you my procedure for it, although i use 2 part paints at work.
I'm assuming your car is in a factory finish in 2 part paint. and you WANT to primer it.
1.wet sand down all the old paint, the aim it to de-gloss it, but dont go through it.
so use like P400-P800.
2.mask the shit out of it cos you dont wanna be cleaning up overspray.
3. wax and grease remover in one hand on a wet rag, dry cloth on the other hand, apply and wipe off, your getting all the was, grease, silicone and anything else off
4.tack rag it to get all the lint and dust off, at the same time used a airgun to slightly blow it off.
5. spray it, generall acrylic primer is 1:1 ratio thicker will cover, but you will get dry spray which is hard to sand. spray it however you want, its acrylic, its solvent based, so it'll melt into the other coat and if you apply heat it'll also soften. so you gotta let it air dry. you normally need around 3-4 coats depending on the situation, if you got body filler on some areas best to give those areas more coats.
now assuming its all done priming
now we get onto prep and paint
1. get a guide coat, black paint and dust it everywhere or 3M has a dry guide, which is black powder.
2. wet sand the primer using a soft-medium block with P400-P600 untill the black is gone
3.mask the whole thing up again.
4. same as priming, wax and grease, tack rag
5. btw, you should have a vapour mask.lol paint it, you can put as many coats as you want, more=better because you dont wanna sand through it later and have to paint it again. i'd go with 6 wet-medium coats.
6. let it all dry. 24hrs at least...
polish time,
1.leave it all masked up, sand it back with a soft block with wet 1200-1500.
2.and then just sand it randomly in a circular motion anywhere you can with 2000
3. take out your polish machine, corse polish, with wool pad and polish. works best with acrylic, acrylic will resoften with solvents, and heat. the aim of the polish is to heat it up, and the same time let the polish take out the deeper scratches. it takes time to polish, you'll know its done when its very glossy.
i think that should be it, missed abit here and there, but its just a small write up.
again, this would by MY ideal way to do it.
i paint cars for a living. its time consuming...
