What sealant for this leak?

[dkrukosky]

So I am trying to get the leaks stopped so I can start re assembly. I have these pesky leaks that I was trying to track down it appears they all come from the same issue. take a look at the image

There was an old skin repair where they layered new skin over the old skin. from mid seam up to the zip D awning. it runs from above the door all the way back to the rear end cap. I have removed all the olympic rivets and replaced them with Buck rivets in hopes that this would stop the leaks but it did not. so now I am wondering what sealant would be best to use to stop these leaks.

I have available trempro 635 (vulkem)
parabond

I just did some reading about Captain Trollies creeping crack cure and it sounds interesting.

should I use a combo? Also what is the life expectancy of these products? how often do they need to be removed and re done?

Thanks

Few of my leaks originated where I thought. I took everything off the top and replaced with new. I looked for loose or missing rivets and found 5 missing rivets under the awning roller. I found a few loose rivets on the awning rail and some missing rivets on top. I sealed seams and removed inside skin to seal some skin rivet and seam leaks. I used Vulkem 116 gray for all the aluminum sealing.

Some leaks, I couldn't even see until I removed the inside skin and cleaned the insulation off the inside of the outside skin. I had no luck guessing and messing.

I actually have all of the interior skins out right now. Much like you I had a few missing rivets those have been replaced. so I am reasonably sure that the leak is coming in under the outer skin repair. I am just not sure what sealant will do the best job on this type of leak. I have no experience with these sealants so i am wondering about there longevity? shrinkage? do they get brittle?

I'm not the sealant expert. I was told Vulkem 116 was a good sealant to use. I have had good experience with it. If I do more sealing, that's what I'll use.

Maybe some posters who know more than me will add to the thread.
