Cudaman,

I know I could do it with a gun BUT, I chose the roller method for a lot of reasons:
1) I don't have an HVLP gun
2) I don't have an air compressor that can support an HVLP gun
3) I don't have any respirator equipment
4) I don't have anyplace big enough move around free enough to spray a car, and then $650 is way more than I can afford for paint at this time. Not to mention about another $1000 for all the other equipment, listed above, I don't have.

These are the same reasons that most everyone else doesn't spray their cars as well. At this point for me, that $1000 or more listed about what it will take to get my car on the road, if I spend it on just paint, I might have a conventionally painted car, but it still won't be roadworthy. If I roller it I can get it roadworthy, AND have a decent looking car.
