I think Gene is using the same stuff and it seems to be made to be sprayed on. Haven't tried rolling it on at all. Compressors and spray guns are pretty cheap these days. The porta - garage was $220 at Peep Boys, plus a tarp and and you are good. Or at least that is what we are planning. The porta - garage has a front and back door (that zip shut), and you got an instant paint booth. Talk about your shade tree mechanics.
But the hidden monster routine is pretty cool. Nice when they look at the flat broke black paint job (black primer) and you get all roasty on the tires.....
