depends how you want it

hammerite is ok, but you will not be able to paint over it so this would need to all come off for what you have done

but the basis is simple alls you need is a compressor and gun

with mine i cleaned the hole underside using a hard brush and panel wipe and it comes up looking factory

then for awkard places i used some metal wire wheels on drills etc, and i just went across the rest of teh car to get some form of key

once all ready mask the entire car, all holes inside the car etc, everywhere you dont want paint to go

stonechip i used the hammerite stone chip in a schultz can as this can be painted over and leaves a rubber texture

once that was dry o just used normal 2 pac paint, i went down a local paint suppliers and got 2 litres of mallard green with the colour code i gave them, thinners and actiavators, also some laquer

you will also need a mixing rule and some plastic cups, mixing the paint is very easy as you go by the numbers on the rule

make sure you have a very very good mask, i bought mine frommachine mart with filters for 2 pac but still after half way through painting the filters were failing and i started to get very high, fumes are a killer especially laquering and you do not want to breath laquer in, if you think about what it does to cars paint when it sets think what it does inside you lol

other than that paint, then laquer, obviously wants paint dry lol
