I had the gun for a couple of months and kept it on a shelf in the shop. I took it off of the shelf to use it and noticed that the paint on the gun was scratched just from minor handling...YES the gun is painted, over plain aluminum? surface! I had to keep it on the shelf because it doesn't have a top hook to hang it from.
The regulator is very touchy. Marginal at best.
I sprayed a small job and it did do a very nice job so if you don't mind a new gun that looks 20 years old and you have a decent regulator, this is not a bad choice
