Having bought a TT airbox I set about trying to smooth it. I've finished removing the mould lines / blades that run across the airbox. As you can see resut is somewhat less than smooth. It is in fairness difficult to completely smooth it without spending an age sanding though. A few of us at Inters were discussing painting the inside with some sort of paint to completely smooth the rough edges. Anybody got any ideas? Halfords do a vinyl paint which might do the trick?
