I have an old 12' Sears gamefisher. The fiberglass hull has some minor damage to be repaired and a couple holes to be filled that the prior owner drilled. The prior owner "painted" this boat at some time in the past with resin. In some places the resin is over 1/4" thick, but for the most part it is thin. I don't think he prepped the hull well before doing this as much of it is cracked and lifting off. In other words, it is a mess. If this was a 22' boat instead of a tiny 12' unit I'd toss it. I am going over it with a 50 grit wheel on an angle grinder and that seems to cut it away fairly well. My orbital sander was not doing too good a job on it. Of course I am cutting into the fiberglass a little bit, but I am being fairly careful. I do plan on a couple new layers of glass on the bottom and transom and a single layer on the sides.
If you have read this far here is my question. Am I being anal about removing all this old resin? In some places it actually seems to be attached well. In other areas it comes off in large pieces with a scraper. Remove it or sand it and lay new fabric over it?
