ok, so whats involved with prepping the panel? for example i have decided to go back and do the roof again cos' my mate did such a crap job on both the bog work and the paint (the corners of the front and rear screens are round and they are meant to be square so the chrome trims dont fit up, the roof has a massive wave in the middle on the drivers side and the paint is so frikken peely, looks like he used a roller to apply it) can i get away with scotchbrite, or will i need to really dig into the paint with some 40 or 80 to get the poly to bite in? in fact, how much prep do i need to do on any panel to get it to stick?
how hard does this stuff go and how quickly? is it like bog where you have 10 mins of soft, a few hours of medium and then its rock hard? should i be looking at preping/spraying/sanding one panel at a time or will it be ok to hit, say, one whole side of the car and take a few days flattening it out?
appreciate the help guys. also on the "price vs product" thing. i have always been of the understanding that even crappy motorspray paint can yeild an excellent result, you just need to know how to use it... but with a higher price, the more the product works for you. i dont mind paying more money for something, but only if it takes away some of the 'idiot factor' i.e. my inexpierence.
