Question,

I'm in the middle of a frame off on a 1978 Sovereign and thinking about sealing seams and rivets from the inside. I know there are ton of posts on this. Planning on using Trempro 635 but wonder if anyone has also added the Eternabond tape on the inside seams? Noticed a couple threads that discussed installing on external roof around vents but nothing on the inside?

Will it be as effective with the "sticky side" against the possible leak?

Any comments are appreciated.

Thanks

Consider flex seal spray?
Rust-Oleum makes the same product but less expensive.

Probably something like gutter seal would be better since you can paint it on. I would clean the seams really well. The older trailers used some sort of oil based putty that would most likely keep new sealants from sealing properly. Eternabond tape needs some heat to help it seal. Might be something like a hair dryer needed to make it conform and stick.

Is that stuff legit?

Anytime I see that sort of sales technique I write it off as snake oil.
I think they make a boat hull out of a screen door and seal er up. lol

I have used it on internal seams and will never second guess it. It's truly neat stuff perfect in this application!
It is a permanent solution!

Gutter seal makes sense. Goes on aluminum and is exposed outside 24/7. I'll look into that. Maybe that and top it with tape?

Thanks for the advise

Lexel gutter seal is awesome stuff! I asked about this on the forums a while back and received glowing recommendations.
It's awfully sticky, and tacks almost instantly. There is a learning curve but the stuff apparently lasts forever and will not yellow or peel!

Thank you!

I used Lexel on the exterior of my trailer 2 years ago. It's tough stuff!

A friend of mine started using Lexel on his roof instead of Dicor. IMO, Lexel is far superior because after 4 years it still looks new and is flexible, in full exposure direct sun in FL.

ps: That black sealer that was originally used on the interior is asphalt. It is similar to roof patching asphalt or damp proofing asphalt used on masonry foundations. Some of the older trailers may have "fibrated asphalt", meaning it could have asbestos fibers in the mix. Be careful!
