Onto the next job

Ok so now I've sorted a few more things out on the 2b, next job is paintwork, I'm quite handy with my spray gun and compressor, so I want to respray the whole car, but the thing that concerns me is 1stly the arch extensions, on the passenger side where the arch extension joins the arch it has cracked the paint all the way around, how would I stop this happening in the future, 2nd the same has happened down the center line of the bonnet, what paint have you guys used, I see gelcoat is used a fair bit
