don't use cheap spray cans like mine. It looks good for a few months then fades to shit. You can achieve an ok look with cans but you need a good technique, a lot of patience and it can cost a lot as decent paint in a can isn't cheap.
At the moment I'm painting mine with GMH matt which cost 47 bucks for 4 litres and a compressor (cheap cans cost me almost 150). There are plenty of ways to do it on the cheap but it all depends on the end result you desire.
Me, I want rangi matt black so it's always gonna be a cheap paint job.
