I called around and got a few quotes on the soda blast, the best one came in at $2800.
That’s about 3X what I was expecting, so I started looking for an alternative.
There are a couple of products from “Peel Away”
Peel Away® Marine Safety Strip - 5 Gallons
Peel Away® Marine Strip - 5 Gallons
No solvents, no fumes, environmentally safe, won’t damage the gel coat, blah blah blah.
One looks like it will take the surface down to the gel coat, the other looks like it will leave the barrier coat intact.
The video states that if applied and pressure washed off, the process takes about 4 man hours to complete on a 40 foot boat. That sounds peachy, but I don’t believe it.
Anyone ever use this stuff?
The reviews I’ve read have been good, but they are few.
Thinking about using the stuff that leaves the barrier coat. Strip the old bottom paint this fall and fair any place that is undamaged and dry, but needs it. Let the rest of the hull dry out through the winter, fair what’s left, scuff sand, and apply a couple of barrier coats next spring.
Any better ideas?
