Very interesting!
Do you mind if I ask how much the fiberglass raingutter cost? Also, do you have more pics/closeups of how you glassed the gutter to the top? Did you just use resin between the gutter and top to glue it together, or did you also use some glass cloth to strengthen the bond?
I'm not very far away from Portland, just north of Albany, so a one piece gutter would not be too difficult to transport.
So the raingutter isn't cheap - $295 (Link -
Landcruiser Specialties on the Web)
But I compared that to the SOR cost of a finished top with fiberglass raingutter - $2700 and figured that I would virtually have the same product for a lot less.
Again, I'm not a body work guy but I did a lot of research. What I did (based on what I read) is to scuff up both surfaces that would come into contact with each other, the inside channel of the raingutter and the underside of the dome with some 40 grit sandpaper.
Next, we foam brushed on a resin/hardener mix.
Once both surfaces had the resin mix applied, we added some high density adhesive filler to the resin mix until it was roughly the consistency of peanut butter. This stuff has a pretty quick curing time so we had to move pretty quick at this point. We spread the goop into the outside 1/2 edge of the raingutter (see pic) and dropped the dome on top.
After this, we took a couple of zip-loc bags and filled them with the mix. We cut off a corner on each like a pastry bag. I worked around the outside, my friend worked on the inside basically "caulking" in the edges all the way around. Wearing disposable nylon gloves, I just ran my finger along the edge to clean up and smooth out the excess. This stuff dries like a rock so you don't want much build up that needs to be sanded down. And "no", I didn't use any glass between the 2 surfaces.
Finally, we clamped the front edge all the way across. We used some garden stakes that I had laying around so the clamp would have something to bite down on but any type of dowel would work. Also, we put wax paper between the garden stakes and hardtop as to not permanently bond the garden stakes to my top
The product I used is called West System #105, #205, and #404.
Hope this is helpful.
