Ever heard of blasting bottom paint off with baking soda? There's a local guy here that has perfected the technique. It doesn't damage the gel coat. Some of us are making plans on a group deal and a day at the crane this spring. Then comes the VC-17
soda blasting?

info pls
Doyou have any info you can share regu soda blasting, how does it work , is there a specific soda to use, what psi do you blast hulls with...etc

baking soda
You know as much as I do about it. I was just wondering if anyone else has had it done.

Soda & Abrasive Blasting
Professionally, I design Pneumatic Conveying systems for industrial applications. Soda is actually slightly abrasive. But, if you drop it into a flexible transport hose along with enough air and it becomes highly abrasive. The airflow inside the hose creates "velocity". If you move the soda at the proper "velocity" it will certainly remove whatever you desire. By testing this at various velocities you will be able to select the proper velocity to accomplish your task...without damage. The soda actually is "friable" (shatters into thousands of smaller pieces upon impact). This would explain why you can develop a fine control when using this method. Hope this explanation helps you understand how this guy "did it". No real secret. Cap'n Karl

Not PSI...VELOCITY
Sylvio: It is not the Pressure (psi) that is important. Pressure has absolutely nothing to do with this. Velocity is created when you move air through a pipe (orifice, tube, etc.). The more airflow you put through the same pipe...the higher the VELOCITY of the air. Velocity allows you to "pick up and convey" (called Fluidization) a dry powder or particle. You could produce enough Velocity to move 3" diameter rocks. Think of your gasoline powered blower. Same principle. This guy simply chose soda...it has a known "friability" and will break up without damaging the underlying material or layer. You cannot get this benefit with the use of sand. Cap'n Karl

Thnx Cap'n
I didn't detect any negativeness or a down side in your information. Sounds like I should go with it. It has to be a lot easier than sanding!
