Soda Blast

[eegs2k]

Aussie - The guy told me it would be too rough to not paint. Said it would be the equivalent to sanding it with 100 grit paper. He recommends it get filled and painted.

Maybe others have different opinions, but that is what I was told.

alot depends on how the bottom was preped when it was initiailly painted. I saw one guy use chemical stripper to get all the paint off, then wet sanded and buffed the gel, it wasn't liek the top side, but it looked better than it did before. If the bottom was properlly prepaed, odds are you will need to recoat or paint. One of the local paint shops around here is using hte hard epoxy teflon paint for sailboats with good sucess.

Have you tried soda blasting or commercial hydro blasting?

We soaked the bottom of a Renkin with paint striper and then used a power washer with 5,000 psi and 90% of it came off and then we hand sanded the rest.

Also toilet bowl cleaner has muriatic acid in it and it will remove paint / galvanize if it gets on it and is only a $1 a container. I have been using it on my fiberglass for over 10 yrs to get rid of the brown water stain we get here.

I even use toilet bowl cleaner on my aluminum john boat to clean the bottom after letting it sit in the water all season long, it loosen up the barnacles and then I power wash.
