Surface prep question?

[G.T.]

Ok Vlim and Jerry, as much as I appreciate your input, I'm not going to get caught squeezing cats over these drum magazines.... .... Although there is an ample supply of feral urban felines, and I do like your train of thought, both my German Sheppard and wife, say no! So, I'm going to try the blast cabinet and see what medium works the best? I have to do extensive masking as well as there are only a few interior spots that need treatment and polishing... Abrasives hand held, are too labor intensive, too expensive and waaaay too slow! Best to all, til….lat'r.....GT
