I have just bought a good DIY compressor (14 CFM/130psi) and a budget spray gun from Machine Mart to have a go at spray painting, I have just painted, using rattle cans, a new fuel tank destined to be fitted to my Escort project, and I severely misjudged how many cans I would need to achieve a good coverage and finish etc etc, and it would have been much more efficient and maybe a better job if I had used a spray gun. So Id like to "have a bash" as they say. I have watched the videos on YT and read a couple of mag articles, but I am struggling with what paint/thinner combination I can use. Forgive my nievity, but can I simply buy a tin of Halfords finest enamel black and add some thinners, then go and spray a few cardboard sheets etc etc. And whwere will I find the info on what ratio of Paint/Thinners to use.
