Hello - I have a house sided with cedar and I had the cedar blasted last year with corn blasting media. it looks fsntastic but then our painter came and power sanded two boards for some reason. so now the sanded bosrds dont match the blasted boards.

I am thinking of renting a small hand sand blaster and fixing these two boards so they match the others. does this make sense? any recommendation of material and grit i should use? i was thinking sand and 100 grit?
