When you guys do a frame, do you try and sand blast the inside of the openings or just price for the exterior finish? On this frame I tried to blast as much as I could get to. The undercoating was a bear to get off in some places.. As for Pools, I am in Indiana not Florida... Not to many pools around, hotels maybe. I will postmark with them. Is there someone who can help out me out if I land a pool. I will need you knowledge!!! After blasting the frame, I hit on it with a rubber mallot and dumped out what may have blown inthere.
