Forgot the stripping stage. That added another hour. You won’t have to worry about that part. All depends on the finish from the vapour blasting. As long as there were no deep scratches you need to get rid of you can probably start at 800 grit or go straight to buffing. I bought the 6” bench polisher from Princess Auto. It does a good job but it takes some time to figure out how to position the piece as it is large compared to the disc but it can be done.
Thanks! I got a similar unit from Busy Bee but I’ve never used it. Anyhow - gotta learn sometime.
