Proper Tool for grinding blisters
I'm planning on using the dremmel for grinding out some blisters and voids in the fiberglass matt of the boat bottom. The only concern is that due to the high rev, the fiberglass will tend to be melted and that will inhibit any penetration of the epoxy repair into the mat. Not sure if that is significant. All the gelkote has been peeled and there only remains some remaining blisters in the chopped mat.
