Sand Blasting Anti-fouling ?

[abl1111]

I had a local sandblasting company take a look at some sand blasting I wanted done and we got to talking about sand blasting the bottom of the boat to removing anti-fouling - he gave a very good price and when I asked about 'dangers' about blasting and gelcoat damage, he said he has done many many boats with no issue.

Is there a real concern having a sandblaster remove bottom paint ? I certainly would not use it if there is. My plan would be to remove bottom paint and then epoxy seal…

Thx
