What's the best adhesive to use on fiberglass?
I was going to attach a wooden plate to the interior raw glass to mount something on and I'm not sure what to use.

3M 5200 Marine adhesive
Just squirt it, duct tape it in place and 1 FULL WEEK later remove duct tape.
It aint goin' nowhere!!

Take the wood and coat with epoxy and let set up. Take the epoxy resin and mix in some filler. Make into a peanut butter like paste. Apply the peanut butter epoxy to the wood. Is epoxy strong? I think so.
P.S. Don't forget the hardener.

FUNNY YOU SHOULD ASK THIS...I just had the same job...to fit a nice circular wood frame clock to the inside hull...however i did not use glue as such but cheap silicone at $4. a tube. The same stuff they use to seal gutters and downpipes...in clear.'
I cut a circle out of a nice piece of 5/8 inch pine that was a bit smaller diametere than the clock. The clock is designed to hang on a protruding screw. I fitted the screw first then siliconed the wood to the starboard hull forward of the side window and close to the mirror [ 
]
Because it is not glue it has to be held in place for 24 hours. I simply used the gaff pole business end jammed onto an old woollie agianst the port side cushion, while the butt end pressed against the wood disc...and then carefully departed the scene to not bump anything. by tomorrow it will have dried and stuck and stays rubbery. If you have to later remove it, just slice with a sharp knife between the hull and the wood. You can't do that with glue. To stop the clock swinging sideways, placed a round head screw in the wood at the lower edge, but still hidden. Drilled a shallow scoop on the back side of the clocks wood frame so they match together. then its a simple matter when its all set to slip the slot of the clock onto the top screw and push slowly down until the bottom scoop meets the bottom scre head. the clock frame is then flush with the stuck on disc. And is removeable to change the AA battery. Hope this helps.
any other fittings that do not have to carry much weight can be done the same. Like my nice sailing ship key board. That silicone will not let go...whenit has cured for a week, only a knife will get it off...and no holes!.

Sounds simple and easy.
Just need a big enough hammer to drive it through the fiberglass then I can mount my pump on the board.

Amazing how well velcro sticks to the carpet on the Mac but have always used Sikaflex marine for sticking things and nothing has let go yet and only use the marine grade cos it hardens faster and harder than the GP grade.

I was wondering if anyone has tried Gorilla Poly Glue on the raw fiberglass. I was thinking of using it to mount some wood screw surface for bilge area. Fully waterproof and very strong stuff.
