I have used two different brands.
Brand 1 would unroll very easily after a dunking in hot water.
Brand 2 would never ever unroll. Fifteen years later they are still coiled up the way I bought them. I hung them on the clothes line in summer and they still stayed coiled.

i already have them on my ls but have heard from others and think it would work if you got some steel angle and pushed it into the groove in the strip then leave it in the sun it should take the curl out of it then youl have a straight piece to work with or even layit in the sun with some weight on it to straighten it out
