I bought this as a filler with fiberglass resin and 30 minute epoxy. It does work. The Fiberglass resin really gummed up the paper and when added to 30 minute epoxy it really rushed the cure time to about 7 minutes. Never seen that before. Once it set up and cooled off (I measured the epoxy/hardner in equal amounts with a digital scale) it became very brittle and was able to basically scrape it off flush. Easy sanding... This job is not a critical job just filling in some holes in an old fiberglass boat helm. I dont know why the glue set up as quickly as it did. The first batch I mixed was perfect(No fumed Silica). This batch not so much. Guess I shoulda took chemistry in High School. Excellent product. Any faults are mine. Not theirs. I'm learning as I go.
