What are you using to seal up the turret cover?

[spankybear]

I see the TM calls out a aerospace polysulphide sealant to seal around the top and screws. I was wondering what you people are using?

Thanks

I use loads of silicone. Around the hole before I put the cover on. Around the bolts before and after I tighten them down. Around the lip. I remember that aerospace sealant. You had to mix the tube by hand and it took a long time. We used it on aav and lav antenna installations.

Nylon or other 'smashy' washers under the bolts will seal those. I had a persistent leak and it was a bolt leak. Drove me crazy to find it. The plug is sealed with DOW U-428 windshield sealant because I do not intend to ever remove it.

So far I have ordered some foam strip from Mcmaster Carr. Its as close as I can find that matches the stuff called out in the TM. I ordered some copper crush washers also from McMaster Carr. I agree that there could be a leak from the screws. I picked the copper crush washers because 1) they should make a good seal between the surfaces. 2) stronger than plastic and 2) they have a smaller outside diameter than the head of the screw. Theory is I can get some type of sealant under the head of the screw. Maybe overkill but I DO NOT WANT THIS TO LEAK! I did a lot of rust repair.

I am also going to install a windshield. I have been looking and I think I am going to use 3M Auto Bedding and Glazing Compound around the gasket where it meets the body. Again I do not want leaks. But I do want to be able to replace it if needed. Big flat up and down windshield is gust screaming to a rock crack. Links to st stuff I have ordered .

I am looking around to to see that type of sealant people have used on the around the edge and screws. I would love to use the stuff called out in the TM but it's a pain. I even used the stuff at work but unlike what Suprman used it comes premixed and frozen at -60° F and needed to be used within 2 hours.

The windshields dont seem to leak. Its like an old vw type. Just pushes in and you work it with a piece of string to get it all the way in. No glue used.

Mine doesn't leak but I might want the truck to float up-side-down...

Anyone actually just patch up the hole with a new steel blank welded in? Like bodywork. I've done it with removing an aftermarket sunroof on a VW. Patched, skimmed, primered and painted. Just thought it would be a good way to eliminate the honking great hole in the roof.

My cover was leaking through the factory flat sealing strip. The way I parked was allowing a small pool of water to build towards the back of the cab and that is where the original real was overlapped and allowing water to go between the seals like a labyrinth.

I went with a spool of neoprene O-ring and made up two pieces. Each either side of 4 ft diameter. One on the outside and one inside the bolt pattern.

Seals great but highlighted other leaks in the cab

I used 1" thick, closed cell phone tape about 1" wide as well. Ran that all the way around and overlapped with a bit of silicone in the gap to ensure seal. Put a dab of sealant on the bolts as well. Has not leaked since. Incidentally, it had the original 1/4 thick rubber strips with matching bolt holes in it, that leaked terribly.

I'm planning to welding mine shut and doing some filler before I sound/heatproof the cab and build my upper console.

I bought the stuff he uses but have not done it yet.

After lots of research I used 3M 740 UV. Paintable sandable and extremely durable.

I "wet set" into a bead then sealed the recess around the cover as well as the new 316 ss bolt heads.
