A8ksh4,
A couple of thoughts and questions about your fiberglass.
1. I used the Tap Plastics resin this summer. Did you get the quick set per chance?
That could be why the epoxy is setting up too quickly. Also for the area shown in your photo a few ounces was probably a bit excessive and I have found in some cases that mixing too much resin at once can cause it to set up really quickly in the container. Hence the heat and smoke.
2. You might use one or two inch paint brushes to put epoxy on the smaller areas. Tap has those brushes fairly inexpensive. As someone else suggested, possibly glue the glass down first. Use 3M 78 spray adhesive. It is made for polystyrene and won't eat it.
3. To keep edges from fraying too much, run a strip of masking tape where you need to cut the fabric. That way you can get a clean cut. Then when putting the epoxy on the glass and over the tape the adhesive on the tape should quit working and you can remove the tape from the fabric and finish putting epoxy on those seams.
Hope this helps.
JJ
