I bought a HobbyAir system from Eastwood a few years ago. There are additional
considerations beyond comparing its price to that of having a car refinished.
forced air system has applications other than painting. Long welding stints are
much more pleasant with a source of fresh air. Same with sand blasting. The
system also remedies a continuing problem I've had with both these processes:
fogging glasses and goggles. I never considered these advantages when I bought
mine. My sole concern at the time was poison paint. Had I known these other
advantages, I wouldn't have waited as long as I did.
