Some of the dirtiest paint jobs I have ever seen came out of a high dollar freshly serviced paint booth. Just saying.
Most of the dirt comes from the car.
I don’t doubt that. Some of the worst dental work I have ever seen has come from the “fancy dental offices with the gimmicky marketing.”
I don’t need a perfect shop, a separate garage from the house, 2 car garage with more space would probably make painting a car much less chance of problems.
Me using quality materials with a cleaner space makes it easier for me to do quality dental work.
