You can buy a small tankless air compressor (Campbell Hausfield) for about
the same price as a top quality Wagner.. The spray guns cost from $40 and
up, but I recommend the HVLP gravity type (paint pot on top) for most heavy
I recommend the tankless for the guys who don't have a lot of storage, but
there are also small pancake or twin hot dog tank types that store easily.
For your detail work, like the security bars, you can get a small detail gun
for under $30 from Harbor Frieght.
