Yeah mate they are Nightmare racing plastics. Mark makes the best KX green around.
That tank .... man .... when I got it, it was mostly white and looking crappy.
That is the result of about 6 hours of running from 320grit right through to 12000 grit wet and dry.
All hand wet-sanded. Thats how I have done many tanks now. It's easy as, just takes about 20 beers
I will take some piccies of the other side and throw them up soon.
