jelly... :squigglemouth:
Don't be yet... its still a theory at the moment...
i have some acrylic sheets on it now, but because the is moisture primarily on one side it has warped... so may have to find something else.. may be sintra (pvc)
I use cut styrofoam (per Lindsey's suggestion) over my sump in the garage... it works perfectly... its cheap, won't warp, and also insulates in the winter.
