$249 Paint job @ The Local Shop...Worth Doing?

Myself ..
I would check out the work they are putting out and while there ask how long the painter has been there painter also see what paint they use.
Then tape it up and hand it over, and if you think about it -
for a few hundred bucks you get a booth and a good arm with the gun
If there is some problem they will have to fix it since it would be paint and there liability (at worst they re shoot a panel) and its no sweat off your back.
If you had a booth I would say why not go for the learning experience and give it a shot.
