Thanks for the comments. My B-I-L tipped me off to using sand and high pressure
water instead of regular sand blasting. I had never heard of it, but some
videos on the web make it look plausible and relatively inexpensive. Nice thing
is no dust so no issues with silicosis.

I may go this route in the fall, still digging for info.
