henry rifle do not give up you will get it. i did this for aliving and painted about one car a week and some some touch ups to. then go home and paint planes and cars at my shop a hang out at my friends a paint stuff at there to. never painted much in a real booth but a lot of home made stuff and it all boils down to air speed to move out and over spray it would hang up and alot of time drop back down this would make for dry spots the roof hood and deck i would start from the farthest panel and work to the draw this would be the ex fan sometimes i would thin out the last coat but it is much better to leave the last coat open longer this helps so thinner do not get trap down and helps with lay down but dirt may get in a lot of time i would lay the second coat out wet and let it set up good to let the booth clean out then loosen up the last coat a bit or go slower on the thinner if i had some and put it on wet and slow it would at times not lay out supper flat but i sanded and wheeled out most of them any ways
