: 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.

I ended up with two areas where the epoxy did not cure. About 3 feet along one side of the hull from the keel to the shear, and an area about 1 foot by 2 feet near the bow--both on the same side of the boat.
I decided to bite the bullet and strip off all the glass. Then I will clean it all up down to bare wood and start over.
Glad I caught it--the fill coats made it look solid, but the boat would not have held up.
Already have about 1/2 of the glass removed.
