Very nice job!

Did you end up doing the sides ?
My top is wore and my sides look like they have seen better days.
I want to replace the whole seal.
I need to adjust my shells and I'm thinking that new bag seals before any adjustments.

The MSDS says it's polyurethane. There are a number of 3M products of clear polyurethane with different adhesives.

It is unlikely that they make their own tape, TEARepair inc. is listed as having 1-5 employees and 500K annual income.

I inherited a TM from my Uncle. Love it, but needs some TLC. It was stored in Texas and the Bag Seal deteriorated over time. I was looking at patches, but it is very far gone. Does anyone know where to find replacement, or can recommend an alternative? Thanks!

Gribnif -

This thread seems to be aimed primarily at repairing the bag seals. If you are thinking of replacing them (rather than repairing them) you can use the Search tool with the term "replace bag seal", to find a lot of good information.

Make sure to check out everything inside the seals thoroughly before deciding that only repair patches are needed. The 13 year old seals on our used unit looked bad with a lot of mildew and hard to get them clean looking. But there were no obvious holes or tears. And there was no visible water leaking past the seals into the living area of the camper either.

But when I investigated deeper, I found that water had been penetrating inside the seals for some time and most of the wood strips that the seals are attached to (inside the wall sections) were completed rotted away. Some sections of the wood were still wet inside there. And most of the screws holding the outside trim pieces (around the bag perimeter area) were rusted away, as they also are screwed into the same wood strips. Finding these screws badly rusted was the first clue that something was wrong inside there.
