Thanks for all of your help, appreciated.

I've dug out an old VW Campervan model, only a little thing, to practice a respray on. My reason for this is, if I cock it up, it doesn't matter.
Will normal spray paint from Halfords do nicely or should I get it from a model shop? Which one would be cheaper? And, might sound stupid, but which, if any, primer do I use. I have never done this before.

Wish me luck lol
