Taking out botton paint

[Billybob]

I hydroblasted my 23'.It had tons of paint on the bottom, and the blasting worked well. I rented the machine, and did it in the driveway.It takes the paint off, but I really don't think anything will allow you to shine up that old gelcoat.I used sand, and it went real quick you could do the whole thing in a day easy.It does impart a flat, eggshell finish to the gelcoat, but I was going to paint anyway and I had some blister repair to do.All in all, it was quick and pretty cheap and easy to do.From what I've heard the soda is even better, a little less agressive and easier cleanup.
