In Response To: Re: Epoxy: Gummy epoxy (Allan)

the approach i used is similar to what allen described. i initially scored the perimeter of the soft epoxy slightly with a razor so it was easy to see. a heat gun was used to apply heat and with the razor i was able to lift most of it off.

i then used 60/80 grit sandpaper on a ROS sander to clean it up and to sand along the edge to cut back into solid epoxy (no heat involved). the 'advantage' (if you can call anything an advantage in this annoying episode) of this technique is that you can really discover the where the edge is because cured epoxy will sand and leave a clean edge. not fully cured epoxy will gum up the paper and smear like bubble gum. don't stop until it sands clear. the other advantage is the sanding create a nice oblique beveled edge for the glass patch.

i used denatured alcohol to test the clearness of the patch edge prior to applying the patch. when you sand it, the glass will look white. if you swipe it with a denatured alcohold soaked paper towel and it turns clear.....than that is how it will look when the new patch goes on....you will not be able to see it and it will blend right in. if you see whiteness, that is what your repair will look like and you are not ready......you probably still need to sand back into solid epoxy.

trying to look at this on the bright-side, i rationalized i now had plentry of practice for the inevitable hull repair i will need to make when i eventually paddle over a rock.
