I had a set of original Torque-Thrusts restored by this guy:
www.akhwheels.com. He blasts them with walnut shells (I think it was walnut shells) and re-machines the lips. My set looks better than new. He uses a very nice shade of silver on the spokes (his "secret" shade) and also sells the proper center caps. I was very happy with the final product. He also has many vintage wheels in stock.
