I have been hanging around the forum for several years as I have built a stich & glue and two strippers.

Working on my fourth boat, I have my first disaster with epoxy. I laid up the outside of the hull about 10 days ago and added three fill coats. I am using Raka 127 resin with their 350 Non Blushing hardener. Doing some rough sanding, I found a couple of spots that did not look right. As I sanded and poked at them, I found soft epoxy under the hard fill coats. I started to pull at it and the glass started to peal off. Under the glass was a soft tacky, gooey layer. As I expanded my investigation, it appears that somehow I mixed up a bad batch of epoxy. The glass is sound on either side of an area about 3 feet long on one side of the boat (about one batch). I have pulled most of the glass off of the soft epoxy.

I figured that the only thing to do is to remove the glass from the area with the epoxy problem. Then I need to remove the gooey mess down to clean wood. Any thoughts on how to remove the mess? It instantly clogs up sandpaper. Any solvents that I might try?

Once I get it all cleaned up, I will lay on a patch overlapping the good glass and that should salvage the boat.

Any suggestions would be appreciated.
