Blisters, yes another blisters thread
Apologizes for starting up a new tread on a topic that,I am sure, has been well discussed here.
Every year when the boat gets pulled out I find approx 20 small blisters on either side of the hull, approx 1/4 to 1/2 inch in dia. 90+ percent of them are water trapped between the hull and the anti fouling paint. I pop them in the fall and let them dry out before sanding and re-painting in the spring.
If I suspect that the blistering has penetrated the glass in anyway, the blister is touched with a dremmel tool, dried out, sanded, and then filled with resin. No filler used.
Approx 10 years ago the hull was stripped of all anti fouling paint and approx 8 layers of fiberglass resin was applied, in an attempt to pre-actively seal the hull. At the time there was not an issue with blistering beyond what was described above. Done in the spring not the fall.
What causes this blisters to occur in the first place?
Am I not applying the anti fouling paint correctly?
Not prepping correctly?
