Have any of you got any tips on making exhausts have that heat discolouration effect on them? I've tried it myself but it looked pants.

Tamiya cover it on their website under the Motor bike section!

I've looked all over for it, but can't find it. Do you mean the tamiya europe site or america or what? :confused: I can't seem to find a motorbike section on any of them. :( You could't post a link could you?

I hope I can :D
