rebonding underside hood reinforcement on a 65

[fredd65]

hello..the bonding on the underside of my hood is loose at spots...anyone know of an adhesive to use?...the problem is two part epoxies set up too fast and not real easy to get it to ooze underneath...ideally, i'd like to use something premixed in a caulk tube...then i could force some underneath while i wedge it up...then set it all down...i checked at the local boat shop and they have something made by 3M that looks like it might do the trick..thanks for any help...fred

Most of the aftermarket fibreglass suppliers also supply bonding adhesive, which is used to bond panel to panel, and bonding strip to panel. It's what was used when your 65 hood reinforcement was bonded to the upper hood skin. It's most likely a duPont or 3-M product, may even be the same as your boat builder friend has, but to do it properly, get the right stuff from one of the aftermarket fibreglass suppliers. You can wedge the gap open between your hood & reinforcement & work an amount between them with a putty knife.

A neat trick I learned to apply the bonding adhesive is to purchase a tube of caulk in the plastic tube. I used the tube from a $ .99 Red Devil painter’s caulk. Cut tip and squeeze out the entire calk or ready your house for the winter weather. Remove the plastic piston and clean the tube with warm water. I then filled the tube with bonding adhesive and applied it with a caulking gun. The trick is adjusting the amount of hardener so that the adhesive does not harden in the tube.

Hope this helps!

thanks for the ideas guys...i think i'll call paragon and see what they have...the bonding adhesive doesn't set up real fast does it?

Nope, but depends on how much catalyst & what the ambient temperature is, it's a catalytic reaction just like the fibreglass layup.

If your not too concerned about originality, My all purpose adhesive that I just used to do what your doing is Urethane Windsheild Adhesive. The stuff used today to hold windshields in. That stuff will stick to anything. I use it everwhere when I need to glue stuff together. It comes in a caulking tube and I am quite sure my hood wil NEVER de-laminated again. If your supplier has a choice of brands, use the 3M.

I used the 2 part 3M stuff in the red box with a black and white tube.I remember having plenty of set up time.I remember it turning tan after I mixed it.I aslo used pencils to keep the hood seperated to apply the mix inbetween the hood and the skelaton.I also circled all the spots I wanted to do with a childrens crayon.I also did one side at a time,Maybee thtas why I had plenty of set up time.Good luck
