it's a hokey garage, with jerry rigged ventelation. The airflow sucks, it's super dirty, it's a really small low ceilings, with an office desk in it for mixing. Not your typical paint booth.
If you're paying to use it, get a downdraft booth, with bake. Bigger the better, and make sure the air supply is as clean and dry as possible. A seperate mixing room would also be a bonus, but not required. And make sure it's clean clean clean.
Now here's the problem, paint booths like that aren't for rent around here, people make a living with them.
If I were you i'd spend the $$ on your axles,(longs, lockers, gears) If you're that desperate to get it sprayed, use your garage and buy cheap paint. it's a wheeler and will get the paint ****ed up anyways. better yet do what chop shop said and rattle can that bitch, it'll be easier to touch up later too.
