Van, I think it depends on the condition of the hull. If something is hidden by the bottom paint, this would reveal the problem, like blistering. The reason to use soda is because it shouldn't damage the gelcoat.

After blasting of any kind I think you ***really*** want a quality barrier coat done... Even soda blasting will leave the gel-coat in a porous condition and I think you will be leaving the door open for blister problems in the future. If you are going to spend the coin to blast, put the barrier on and then use ablative bottom paint to avoid buildup in the future.

BTW, one "problem" with blasting is it will expose any problems you have with the bottom. You may have to fix them before you re-coat. So if you discover you have blisters after blasting, you have to fix that then barrier coat...it could run you more then expected....be prepared for that.

I had my SS OB prop done by Ocean Props and it was fine. If he has to do additional welding to add material due to a rock nick he will charge you a little more but in my case it was only like 20 bucks more. It comes back nice...almost like new.
