Hi hope this is the right place to post this, i've just bought an old tvr been sat for 3 ish years looking for tips to clean the roof up as never had a convertible before also the rear window (plastic) is marked on the inside where its been rubbing on something the last own had on the rear shelf didn't want to try anything yet incase it made the window go off colour or hazey.
