all of libs base info is misleading, i was told tnt was not extruded in this post
From inspection lib has three base materials,
TNT, a clear base inpregnated with florocarbon shit, allows lib to sublimate crazy cool base graphics used on most boards. fixes easily with a ptex candle
swirled sintered, used on the skate banana and sidewalls, two solid colors mixed together. harder and more gouge resistant than TNT. Hard to repair, ptex candle doesnt stick.
sintered 9900, black fast race base, on the la nina, banana magic, temple cummings.
