Saw the FRP panels today at HD-they've gone up to $32/.
Found myself more attracted to the "Thrifty White Board"- like its texture (and its price- 1/3 of FRP) better. Does the backside hold up on moisture? Is it something that could be sealed?
I plan to be able to take off the panels relatively easily (maybe) but I'd like to know how it would handle a humid/ temp changing environment.
