Gorilla glue (polyurethane)

Anyone used this to stick wood to fiber glass.

No, I have not, but if the gel is roughed up I see no reason why it would not work.

I use GG all the time for wood-to-wood and it's amazingly strong. However, I've noticed the price of the stuff has gone up ASTRONOMICALLY. Why, I have NO idea, but it's bordering on prohibitive to use at this point.

gorilla glue expands... careful... when I use it I let it set about 5-10 min, then clamp it.

white glue or epoxy on raw wood... FTW!

Also, it needs moisture to cure. Read the directions.

That's because Gorillas are becoming extinct in the rainforests

PS This is one of the few times when Hamin 'X is incorrect - - - never read the instructions if you're a man's man

I have used this to glue a block of wood to a Kayak and it has held now for two years in saltwater

Good, strong stuff. Ditto the roughening and cleaning of the surface advice. (Assuming you don't need/want to use epoxy or MMA instead).

There is usually enough moisture already present in the air to make it set, but adding water to the joint will speed the cure. Which is the problem with it - there is enough moisture in the air above the glue in the bottle (not to mention the moisture that passes through the plastic bottle) to make it set. Meaning the shelf life it pretty short, so group your projects and use it up.

Some form of clamping is a must (to counteract the expansion), and don't get any of it on your fingers!

Alcohol stove fuel (aka 'denatured alcohol' - the kind you get in the hardware store) will do a pretty good job of getting Gorilla Glue off your fingers and tools.

As to curing, yes, it will *eventually* cure without adding water, but I do seriously think you should add water, as they note in the instructions, since the sooner it sets up, the less likely it will come out of position or that you'll shear the bonding areas. I usually paint a thin coat of water on one part, then brush the glue on the other and clamp them together.

But you're right, don't buy more than you'll use in a 6-month period, because any excess will very likely go hard in the bottle.

Thanks k- Good to know alcohol for cleanup! I will say there's no need for me to go to the store to get some.

I use GG extensively for my other hobby - model flying airplanes.
There are 2 different ones - the yellow one (which will turn even more yellow over time) is a slow cure and then there is the white one which cures pretty quick. Normally I do not add water at all - there is enough moisture in the atmosphere! If you do add, use a spraybottle with water after you fixed the parts together - expect more foaming and faster cure time.
To store GG squeeze the air out of the bottle and store it upside down!

BRILLIANT

Two part epoxy, comes in 5 min. set or 1 hr. Much better than any single type glue.
Can buy at Lowes or Home Depot.

Epoxy is great stuff. Only thing I haven't been able to fix is a brake fluid master cylinder...the ether glycols in brake fluid melted it like magic. I even managed to glue a shift lever back Ono my Nissan 4HP for a season...
