How much SCFM do you need for the touch up gun.
Just purchased a small 2 gal. 2.4 SCFM @ 90 PSI Sears compressor for $90.00 for the shop.
Fairly quiet ... oil type. It fits under my work "bench". They are on sale now (this area) and if you have/apply for a Sears Club card, you get 10% OFF THE $99.00 SALE PRICE.
Most of my use will be air-brush ... but I think I'll try my touch-up gun tonight.
It was a lot less than a good air-brush compressor that doesn't have a tank.
I will pump this thing up and get 10-15 minutes of air brush time before it cycles.
Works for me
Good Hunting !
