I seem to remember talking to someone that tried the hot water trick but in awhile the seam "T" molding soon puckered up again. I think when the plastic gets old and tired it is probably best to replace it. If the locking strip in the joints is still good you can get the orginal molding from here. I think the Trillium
uses the same "T" molding. I think I may buy a roll myself as I have a couple of friends who have Bolers.
SEAM TAPE (Boler)
I ran across this on another site. Might be worth following up.
* Seam tape for sale
The roll contains 150' and will do 4 trailers. It?s exactly like the original. Cost is $55 includes taxes and shipping and you can sell the remainder of the roll to other Bolerites.
