Why not?

 It's a van and yes. the finish isn't that bad to be honest. nothing a cut down between coats won't sort. How do you think the factories do it in your neck of the woods?!
They have to find some way to employ the immigrants! hahaha No only joking. It's a good DIY method that doesn't cost a fortune and easy to maintain.

 sorry VAN, and ive just never seen anyone use a roller to paint a car.

 No that's cool buddy. You'd be surprised how many cars have been done that way.

 does it come out looking any different? like can you see the brush strokes... or roller strokes i guess..

 Well it's only got one coat on it for now but once I've done another I'll put some close up's on.
