Fibre GlastMilled Fiberglass Filler – First Quality Premium Glass Fiber Powder for Gel Coat, Auto Surface, Car Finish & Marine Repair Kit — 1/2 Gal, Dries Clear, Resin & Epoxy Compatible

Excellent product, to increase the thickness of epoxy, and in the process, increase the strength.

Very good product, makes my epoxy stronger when I need it.

Good

I just wish it came in a plastic container to make it easier to use and store. It comes in essentially a cardboard tube which i doubt will last after being stored on my boat.

Works great

It works well for providing structure for resins. You can use it with epoxy, polyester, or vinyl ester resins. Just make sure you are extra careful with this since it wouldn't be very comfortable if you accidentally inhale it.

Chopped fiber or milled fiber is used as a strengthening agent in resins. This product needs to be used with caution because it really is very finely chopped glass fiber and it gets everywhere if your not careful. Eyes, lungs your cloths.I am pleased with this product and would recommend it for the good price.

I use this on boat repairs under the waterline to make a paste to fix small scrapes and fill deep chips under fiberglass cloth. I found it to be as good as any I have used; consistent in size and it wetted out easily.
