Ryno Lining

I have Ryno Lining in the bed of my 66 F100 and I am going to get ready and mini tub the bed and build a custom wood bed floor for it (since it's a style side they don't make wood kits). I need to strip this stuff out and was wondering how I can go about doing this... I'd rather do it myself than take it and have some shop or something do it. Do they make a special stripper for it? Do I have to take a heat gun to it and slowly scrap it off? All I need to do is the bed sides, wheel tubs, and tail-gate, the floor will be cut out so that is no problem.
I'd appreciate any help here guys! I have asked around locally on how to do this and noone here knows anything.
