Default Boat Sandblasting?

I hear people talk about having boats sandblasted. As a "sandblaster" myself, I would think that this would chew the hell out of fiberglass
Does anyone on the board do this type of work?

I have heard of walnut(I think) sandblasting. Maybe slingshot will chime in. I know that he and his brother do this type of work and he was telling me about blasting with walnut shells I think...

I used a pressure washer with a sandblastin attachment to blast the bottom paint off a boat I have. It worked well, with only a couple spot on points that I got a little deep on.

The second boat, I had the bottom paint bead blasted off. It was much rougher than the sandblasting. I had to sand it back smooth afterwards.

Default What we blastin

Just curious as what your thinking of sandblasting ..Old paint , prep for new , bottom paint etc.. Id think it would be good for old bottom paint removal..They say a satin finish is faster than super gloss anyway..I like the fine sand for metal parts ..

Id think you would find more trailers that needed it than boats IMHO just an idea

slingshot does this strip off gellcoat to bare fiberglass? Also w/plastic media do you have to use any nozzles or pot pressures that would be different than regular sand?

Pantera, I have done many trailers.

Over in the UK I had anti fouling removed by high pressure mix of baking powder and water fired out of a nozzle by an industrial compressor - it left the fibreglass completely untouched, but removed all of the anti fouling. I hope that helps a little?

Soda blasting is often done on Vettes.
