I know this sounds rather stupid but does anyone have any advice for repairing a "botched" fiberglass job? I just attempted my first fiberglassing job on a 5.5" "I-roc" and I have seveal sections that are not up to snuff that I'd like to redo.
Most of the problem areas are at the ends of the tubes and along the seam where the first layer overlaped. The first layer was a 6oz wrap of standard cloth with approximately a 1" over lap. The second layer a 2.4oz wrap of fine weave cloth with again about a 1" overlap.
The problems that I have seem to be related to the amount of epoxy resin I left on the tube. I wrapped the cloth around the tube after coating it heavily with epoxy. The tube had been prepared for fiberglassing by stripping the top, glassine, layer to expose the inner kraft tube. I then used a 3" paint roller to further saturate the fiberglass cloth with epoxy. When the entire tube had been coated I used a roll of toilet paper on a paint roller handle to remove the excess epoxy.
The epoxy I am using is very slow drying, about 5 to 6 hours to setup and 24 hours to completely dry. Apparently overnight the amount of epoxy in the fiberglass cloth decreased, probably by soaking into the kraft tube, and areas along the seam and the ends of the tube dried out.
I was wondering if I could cut out these areas or sand them down and then apply glass and epoxy "patches". Has anyone ever had to do this? If so how well did it work?
