Is there any how-to's out there on how to do this? I know you use a motor tool to do it with, but I find out that its easy to get carried away with and thus doesn't look at that great.

If you mean how to give your roadwheels a "worn" look, I use a sharp knife to randomly remove some of the "rubber" and then I pass on the rubber part witn a metallic brush...

I recently bought a keymakers vile set wich is perfect for those kind of scratches and dents. The vile set I have came with a variety off all sorts of shapes and because they are very small you can make really realistic damages to it.

I do a two for one ...I have a very rough file in the shape of a triangle...I use the flat surface to file away the mold seem and then turn it on an angle and remove gouges from all ove the rubber parts using more or less pressure makes this look very random.

not the best picture but you can see the effect .

In addition to nicking and gouging the rubber with a knife as mentioned above, I coat the rubber part with Testors liquid cement. When it is tacky, I roll the wheel between my fingers, which blends the gouges in and gives an overall roughed-up texture. I'd send you pictures, but my little 2 megapixel digital camera sucks at detail shots.

On of my favorite tools is a simple "file-card".
Pick one up at a decent hardwear store.
It is normally used to clean the teeth on large files.
It has very short, stiff metal teeth, that do a fair job of
roughing up the rubber part in only a few minutes.
Then running of liquid cement around to soften and blend it
together, also removed the sometime fuzzies that appear after the
treatment.

works also on resin wheels, just use a little less pressure.

All the above ideas are great. You can also use steel wool to knock down the severity of the knicks and gouges. I use a combination of a dremel bit and a #11 blade. Also, the rear most roadwheel on a tank take the most abuse, and will show more wer and tear than the others will. Lord knows I've changed more than my fair share of them! HTH "Q"
