Hell no! Tarpaulin? Why not just get some wire wool and scratch your car to heck?!
If you want to invest in a pretty darned good fitted car cover with a soft fleecy lining, securing straps & breathable cover then a cover from Hamilton Classic is the way to go. Might be pricey but worth it imo.

Hamilton Classic are also at most of the major shows so if you're going to Ford Fair, Goodwood etc etc they're usually there and usually have offers on. They also do fitted seat covers with the Ford symbol printed on.
