Home depot or lowes has melamine...and for heat use 1 piece of heat tape...my first rack i used 5 different pieces of 3in tape and had 5 different plugs....pain in the ass...i used 2 different thermostats and plugged 3 shelves into 1 and the shelves would never be the same...and 1 shelf got so hot it burnt my girl...so for my new rack {thanks to simple man}i used 1 piece and ran it from top to bottom.
