Tire sanders

One thing I learnt at the Tamiya grand prix last weekend was about tire sanders.

Just strap the tire on and use the pad to 'sand' the top layer of the used rubber off. They really work! It took my old rubber and returned the top layer to sticky rubber.  Actually, this one is a nice one as its used to sand sponge tires too. I'm not ready for sponge yet though! I borrowed the one in the pic as they're are a bit pricey. I might have to stretch my budget to one.
