Quality product from a brand name!

If you really need great adhesion to smoother surfaces, I'd suggest epoxy resin. But if you can rough-up the surfaces, are working over old fiberglass or previous layers, this stuff is great. Measure the hardener carefully and adjust the quantity to your application. I mix 4-6 oz resin with 8-9 drops hardener at 80-90 degrees F and it begins to gel in about 15 minutes. I'm building water tanks for a RV van project. I'm using this resin with cloth and mat to attach and seal FRP sheets.

it is fiberglass. it is half fiber half glass. there is a whole 0.9 pint of it. it is made by 3M!

Bondo resin for fiberglass is the only product I use.

I used this product on kid's bath tub around drain area, after applying product i sand just as instructions said. Then replaced the plumbing for the drain and no more leaks. A big thumbs up for this product.

I bought and used this product the same day. Waiting a full day before sanding and it was hard but tacky ruined my sandpaper so I waited another full 24 hours and same result. Now my canoe is sticking to everything I can't sand it to paint it. I'm very disappointed in this product I wish I didn't waist the money on it. I don't know what to do with it now.

I've bought and use around six gallons of this fiberglass resin to make two bumpers and started on a center console. Your gallon resin works incredibly well, but I only needed about a quarter to finish the console that I'm working on, but this stuff is garbage. I applied it with the correct mixture of resin to hardener and it didn't come close to setting after 2 hours. Next I mixed twice the amount of hardener, waited and it still did not set. Now I have to buy a gallon for a quarts worth of work and also lost a whole day. My question is why are the two sizes different resin? I never would of bought it if I knew that. Next question asks if I would recommend this product, my answer would be that I would recommend the gallon size to everyone, but not the quart size.

I tried using 3M Fiberglass Resin (20122) to repair a cracked hard-sided suitcase. It never cured – not even with a 2X dose of hardener. Now I've got a sticky gooey mess to deal with – possibly unrepairable. This could be due to the product sitting on my shelf for a year or two – unopened, and in an air conditioned indoor closet. However, I DID inspect the can for an expiration date – and found none. Likewise, I checked the hardener – nope – no date. I scoured the 3M website for anything on shelf life - nada. The umpteen page MSDS sheet- nein. I thought to myself “3M is always top quality stuff – if there's no shelf life info, it must still be good”. My bad. SHAME ON YOU 3M for not providing shelf life info or use-before date - especially on a product with apparently short shelf live. This experience has re-calibrated my thinking about 3M. I used to hold them in the highest regard as an ultra-reliable source of professional materials. From here on out, I'll be looking for better options.

Followed the instructions on the can...and it won't harden. Mixed exactly 8 oz with 80 drops of harder, mixed and used a paint brush to cover my outdoor town clock...now I have a goo finish. Paint brush harded but not the clock finish....
