Hi all, i bought some plastic tubs for a rack system im gonna build. After testing for 2 days the bottom of the tubs started to lift/warp from the heat, it was at a constant 88F.Does ne 1 know how i can stop this???Obviously something that isnt going to be dangerous like paper.Would paper run the risk of catching alight form the heat? Plz help me out guys/gals thx Gilbery007
