Anyone use a different self-leveling sealer that doesn't require a special $60 tool just for this one product?Putting seam sealer in each hole is not necessary and will only make a mess. There is actually no need for a seam sealer between the metal and the fiberglass. A self leveling seam sealer should be applied AFTER the two pieces are riveted together.
Also, I recommend drilling out all holes to 5/32" and using 5/32"x3/8" aluminum rivets available at McMaster Carr.
Ah, I thought you had used the 3M Fast n Seal just to bond the metal to the roof, not as a self-leveling sealant.
How many tubes did you use?I used Dicor seal leveling seam sealer, only issue is that it never really gets hard, stays pliable which may actually be a good thing? Wondering what folks thought of the 3M fast and firm product????
@emac what product did you use to paint the fiberglass and was it sprayed on?? Looks fantastic
@emac my top is in pretty good shape aside from slight bends in frame that I fixed. Can you tell me roughly what it cost to get it looking that good? Looks excellent-like new
Howdy--we should keep in touch during this. Mine was rusted through all around, the fiberglass roof was cracked and looked repaired at least twice with different materials, including Bondo/POR-15 putty.Subscribed! I am just now starting this process and this is just the information I was needing. Any alternatives to the CCOT gutter? Mine is rusted through in the rear and rusty all the way around so a replacement is probably needed.
@FWaltersnewbie I only used one tube, less actually but I did not have to do the entire circumference. I removed old dryed out stuff, cleaned it up and applied fresh. I had never had the top on, so some areas that seemed dry I fixed before putting on hard top. You only want a thickness of no more than 1/16 to 1/8 so as to not impede the function of the gutter. Hope this helps
A few years ago I took the roof off of my 1970 FJ40 to replace the gasket between the gutter and body. I found the gutter to be in very good condition. I did not separate the glass from gutter. Mistake. The leak I was chasing was still there, between the glass and channel. Now facing a restoration on my '79. A year ago I thought about swapping roofs knowing how good of condition the '70 was in. I removed the carpet that had been installed in the '79 and it is just a mess up there. I knew when I bought it that some funny business existed as no rivets are visible and the body putty covering them goes over the edge to underneath. So I think I need to order the rain gutter along with the headliner. I will probably order oversize rivets from McMaster so I get a clean hole in the glass. My point is that unless you live in the desert it is a good idea to seal between the glass and gutter using a slow cure sealant to allow rivet installation. Also, without proper equipment, it is better to fit the glass to the channel and drilled and taken apart, deburr all holes, then apply the sealant and assemble. Head of rivet is on the glass side.1/16"-1/8" is not enough to fill in the voids between the metal and fiberglass along the inside vertical edge. The rain gutter doesn't need to be able to hold a lot of water volume to function properly. It's not a swimming pool up there. That said, it shouldn't be full of seam sealer, either. I find that two packs of the SEM 2K self leveling seam sealer is the perfect amount.
