Anyone got any links to online guides or anything??

Id like to learn more about it.

I have a compressor being given to me, and it comes with "a brand new spary gun" which will probably be crap....what kind of differences does the gun make?

Basicly im out to learn. I have a few little things to spray such as my spoiler and bumper, so can practace and learn on those.

Any advice/links?

Cheers
