I have a couple of questions about the glassing you did on your hardtop. I am in the same process only with less of a top. Did you grind the edges down or anything where they mate back up or did you just lay the fiberglass on top and sand it smooth? Also, did you lay any fiberglass "mat" or "cloth" or did you just resin it back together?
My edges don't meet back up because where I cut the back of the hardtop it's 1/2" narrower than where the top bolts to the cab. So did you have to do any major gap filling?
Thanks
My two halves lined up near perfectly. I am anal and did a lot of measure and marking before I cut. My bolt holes for mounting even lined up (by luck) I was planning on cutting the metal lower plate shorter and then marking the holes in the top and just redrilling them. The metal plate would have given me the alignment for the bottom nuts, but luck have it they were all perfectly inline.
I did use a grinder to v groove the edge of the two pieces. I also got some 1"x1/4" strap, cut this into 12" strips. I then screwed one on the lower side joint bottom of window, one on top of window opening (where the large reinforcement area is) and 2 on the top of the roof. I also used about 16 pieces of backstrap about 4" long all across the top.
All of these were attached to the top from the inside out with panhead screws. I then used a grinder to cut them off flush. I filled the gap with a few coats of duraglass (kitty hair) It is a long strand fiberglass and bondo mixture. This is some pretty strong stuff and it really helps with strenght. Air gaps are the killer to any fiberglass work so take it slow and press out all the air. I prefer to use a bit less then recomended hardener to extend working time.
Another good hint is to use rubber gloves and mix the hardener by hand so you can get it very evenly mixed. Then toss the gloves and get a new pair for application.
After the Kitty Hair I laid one layer of woven matt on the bottom. Then after that I glued a piece of fleece to the entire inner part of the roof. Coat or should I say soak the fleece with resing. It took near one gallon on the fleece. Use a body putty scraper to press it into the fleece and make sure it is glued down well because the fleece will try to shrink. I have started on the body work. Which for now will only be a beltsander job because I have to get ready for an Oct. 7th run in Las Cruces with the Cavern City Four Wheel Drive Club.
Actually the belt sander body work looks pretty good. I think I could do all of it and then primer and paint and it would be nice. I am more then likely just going to spray the top inside and out with Rhino Liner and then paint it. Then the body work is less to worry about.
I'll post pics of the progress tom night.
