I’ve been self learning how to paint with a spray gun the last several years. I still haven’t figured out why sometimes it just doesn’t lay down the way I expected. All the variables that Mongo/Greg mentioned. I still enjoy the challenge and find it rewarding. Dust and bugs are always a problem. One trick I saw - don’t know if you did this - wet the floor down and use a little pump sprayer to keep it damp. Really helps to have an assistant for that. Helps Keep any dust on the floor. Edit - can’t wait to see how the cut and buff goes. Also to see it assembled in the sunlight.
