I just had the bottom paint removed today from my 24' Outrage by a company that does sodablasting. Instead of sand, they use food quality grade soda, that's a texture more like salt. The procedure uses relatively low air pressure, water and soda. The paint came right off and there was no damage to the gelcoat. It took a total of four hours, but would have gone faster if the boat wasn't on the trailer. I highly recommend this method for those of you wanting to remove bottom paint. The cost was $400. I had to work hard to find a company that did this work. Here is a link to the company that did my work.

Thanks for the information about soda blasting. It sounds like a good technique for removing bottom paint.

A few years ago I noticed that the most prominent building downtown was looking better than I had ever seen it. The entire exterior (stone) had been soda blasted. The building is now beautiful, again.

A friend of mine who owns a blasting business did a complete soda blast to his 21' outrage inside and out. Very efficient. Good paint job as well.

Soda blasting has many applications. If the operator is knowlegable about the substrate he is blasting.
The Air Force started a sodablast program several years ago, it has been very successful. The soda does not etch soft aluminum surfaces like a grit can and it is very enviornmentally sound.
I am glad to see more commerical companies using it, sounds ideal for marine composites.
