MarineWeld Syringe Review: A Must for Fiberglass Repairs - Got a hole in the corner of my fiberglass shower pan. I used an oral syringe to suck up the mixed epoxy and backfill the hole for added sturdiness. Waited an hour, mixed a little more epoxy and used the flat edge of a caulk/grout silicone knife to level the top nicely. The epoxy is easy to spread, but thick enough that it doesn't flow downward or outward from holes your fixing. Great tensile strength is a plus when I might accidentally bump or step in this repaired area or put pressure on it cleaning it. Love that it resists water and chemicals, it being in a shower that is cleaned often. Great product. I can see me using this if I have any future fiberglass scrapes or holes. Review: Great Value for the Price - works like 5 minute epoxy very strong hold ## Features - J-B WELD MARINEWELD: A specially formulated two part adhesive & sealant that provides a strong and flexible bond that is waterproof, and chemical & UV resistant.
