French polish might do the job of antiquing it, you can always remove it with meths if you don't like the result.

I painted the bonnet and one of the sides black satin car paint and a sort of turquoise that I mixed using Windsor and newton acrylics. I diluted it and tried it in an air brush hopefully creating a bit of patina. 

What friction material have you used in your dampers?

If the conveyor belt doesn't work out, do the same as many of the vintage race cars (and my CK Hartfords) and use oil tempered hardboard, as used to beon the bottom of drawers and back of cupboards. It works perfectly with no snatching as most other materials do.

that is absolutely stunning!!! also what is the mysterious motorbike in the right of the picture?

really cool, great work Jim!

So frustrating that we can't play yet.

Great looking car Jim the paint work is a brilliant job. 👍.
