How do you guys use PVC board? When it is in the sun it curls up like a pretzel. Even small peices clamped down contort in slow motion like a slug covered in salt.
I purchased a sheet of 1/2" white and 1/4" black. About 1 foot was open to the sun on the tailgate, the rest was under the rolltop cover. Before I could get home the first 10" or so of both of them were curled up about a foot and the WHITE was on top. I was hoping to make bat house roofs out of the material but that doesn't look like it's going to be feasable.
Then it occured to me... what is it used for?
EDIT: BTW, any ideas on what I can use? I was hoping to have a durable roof material that didn't need painting and could be formed into a slight bow.
