Hey, thanks a lot for replying

Ok then I'll go ahead and use Halfords make. I'm waiting for the case to come, it was supposed to be here Saturday, never use Sc*n again, because they use crappy citylink (waste of space)
Anyway, I'm going to ask 1 more noobie question. I know prep is everything, but I'm unsure on which bits i should prep how, and whether to sand after undercoat, and between coats?
I've got some plastic parts, which i have sanded down and wiped clean with paint thinner, will these need an undercoat too? Or can i just paint onto it?
Also the metal side panels, should i wet sand them? and how far back? I'm guessing i don't need to go back to the metal, as long as It's sanded a little.
And finally, the metal inside of the case, do i just apply an undercoat? No need to sand?
I'm asking these questions again because everyone seems to give me different answers, and looking on the internet people do a lot of different prep
