Do any of you use powder coating in your restorations ? If so what parts do you most often have coated ?

LOTS of parts get the treatment... Suspension parts, pulleys, brackets, etc. We've seen people go as far as powder-coating valve covers, oil pans and valley covers. Parts subjected to high heat, such as exhaust manifolds, also get it, but a "thermal barrier" is the type used.

On the East Coast, Thermal Tech in Hopewell, Virginia is the shop of choice.
