Well, found I had 1/2 a can of bedliner material left from a previous use and didn’t realize I had. Decided to try some crack sealing/leak fixing. I put a good coat on the side decks, which had been a bit thin in places.
The real "iffy" part is the expansion/contraction in the heat and cool and we’ll see if we go back to leaks or not.
I am becoming a huge fan of sheet goods, especially pre-finished sheet goods like the MDO I used. It doesn’t leak except at joints.
Laminating wood just isn’t my thing.
Time = 1 hour (a good part of it getting the lid off)
