Hi folks, is there a thread on restoring the underside of an SC? Not the wheel arch areas but more how to restore and preserve other 'big metal' under the car. What to paint and what not to paint etc...what the concours approach is.

All and any insights much appreciated

There is now as you've just started one :cool:

After I took it back to bare to check for rust I did mine in spray Rubber on top of some cheap chassis paint, likely not what the factory did or common but works for my car very well and it also acts as great sound insulation :p
