I used to put it on my slot car tires back in the 60's. It really helped them stick in the curves!

From tris: "Can you recommend a good resource or book to discover more about engraving Steve?"tris,It's been a long time since I've availed myself of any book learning, but this one stands out from long ago: Metal Techniques for Craftsmen 1968 by Oppi Untracht.
