Just a warning to all who are thinking about buying a car cover for a project that hasn't moved in months. While I was recommissioning a Renault 5 turbo 2, I decided it was a good idea to buy a breathable cover for it. I bought one of the special breathable car covers from Halfords, think it was called a super cover or similar, cost about fifty odd quid.
Lifted the paintwork in bubbles, looked like blisters. I was later informed by a mechanic friend he sent his back for a similar result. Damage - more than a few thousand.
Apparently caused sweating of the paint, a costly mistake I will not be repeating.
YOU HAVE BEEN WARNED!
