Again, how often will you paint? A plastic garbage can filled with ice
water & a coiled 50' air hose inside does a lot.
Also, one of my neighbors just successfully painted his RV-8 using a
commercial product that's a 3 or 4 foot section of ~1" diameter hose
filled with desiccant, with a small glass sided desiccant inspection
canister (about the size of a fuel filter) after the desiccant hose.
It's inserted right after the wall mounted regulator/filter.
Shall I try to get the official name of the product?
