Bob the one I use said the same...They sandblast and the powder coat and then put in the oven.
The only problem is...I saw a frame that had been sand blasted, but then left tilted on the wall and I noticed a light coat of rust forming on the frame. If they don't re blast and powder coat over the rust...I wonder what happens? Will the powder coat seal the air and moisture out preventing further rust or....or will you have a bigger problem down the road!
