I have a set of those wheels which I cleaned up with Acetone and they came up like new. They are the same as the wheels on the Lazer ZX, the wheels for the SE are as per this photo (no my Mid), they also have a textured surface however they are plated, I haven't seen a similar finish on another wheel. By the way are those Kyosho tyres on the rear, if so where did you get them from
Nice Mid by the way!
