For people looking for alternative ways to remove old paint so that they can apply a new one, checking out this new eco-friendly way of paint removal called eco-friendly soda blasting may be a good idea. Eco-friendly SodaBlasting uses a special formulation of non-toxic sodium bicarbonate, baking soda, to remove paint and marine growth from boat bottoms without harming the gelcoat. So for the people who always want a fresh looking boat with new paint, here is a great solution that you can use, eco-friendly and wiser at that!

In the SodaBlasting process, a non-destructive stream of air-driven, specially formulated baking soda under high pressure is first used to strip the antifoulant paint and open the blister. Then, to prepare the surface for repair and repainting, the affected area around the blister is feathered by split-second, swirled ‘micro-blasting’. This finishes the surface in preparation for repair. The entire process can be accomplished in 1/10 the time as traditional techniques, resulting in a properly prepared surface that is ready for blister repair and painting.
