Sealing From the inside
I have searched and cannot find any info on this subject. All of my interior skins have been removed. I would like to seal all of the seams as an added precaution. What would be my best option? Maybe a think coat of tremco or even silicone?

Well don't use Silicone. Trepro would be ok. The hardest thing is getting all the olde sealant off to put new stuff on.

Seam sealing inside edges of exterior panels
After you clean-up inside exterior panel seams you should first use Captain Tolleys Creeping Crack Cure. It will wick into the smallest spaces in between the panels. Then you can add Trempro or Acryl-R to the seams and create a sealant dam to add to your leak proofing of the inside seams at the panel overlaps. In addition you should also use this same two layer application to the outside seam edges to really have the best protection against water intrusion! This process almost mimics the seal that was used at the factory between panels on overlapped seams and goes the extra step to add sealant at both inside and exterior seam locations. The more sealing you can get the better lasting leak prevention you will achieve. Don't forget to check and seal all rivets using the same technique. Then seal all rails, lights, id plates, etc. to help keep moisture from getting inside! Hope you have a real good experience doing this as the benefit will last much longer than the time it takes to do the work. Ed

Before putting the skins back on, sit in the trailer while it is raining and look for leaks. You will find some in odd places.

Hi. I'm about to seal from the inside. But all the seems are coated in some sort of tar, from the factory I think. I'm guessing this all needs to come off first. Has anyone had experience with this before? What do you think?
