I used Scamps seam tape once before and had to use a hot glue gun to make it stick
I'm redoing a 13' Scamp
right now and decided to find something else to use.
I ordered 1/8" x1" single sided foam glazing tape from glasswarepro.com.
I haven't cleaned the ensolite as I'm still working on the exterior.
I tried a small peice on an area that had been siliconed and it stuck TIGHT.
The Stock # is 74418X1GRY.
With shipping it was about $30.00 for 100'
is $15.00 for 50" plus shipping.
This tape has glue on one side only.
Hope this helps.
