Fiat 500 convertible with a very dirty light-coloured hood -- came up like new. Customer chose 6-month coating rather than 2-year; still good result for a light-coloured roof heading into winter.

An Audi A4 cabriolet arrives for a roof clean and two-year nano protection -- complete with a layer of cat hair. Connor cleans the moss and ground-in grime, applies the coating with a brush rather than a spray, and explains why a domestic pressure washer will destroy a soft-top.

An Audi A3 cabriolet roof clean -- jet wash marks that looked like graffiti writing across the top. Rubbers conditioned, drains flushed, AutoGlym wax on the outside. Came up looking like brand new.

A Jaguar XKR convertible with a beige roof -- the light colour was hiding the extent of the green staining. Fold-line wear, threadbare stitching. After cleaning, Gary spots what looks like a cigarette burn and notes it carefully for the record. The roof came up remarkably well.

An Audi TT in for ceramic coating -- but it has just had a new roof fitted for over £1,000, which Gary says could probably have been avoided with regular cleaning. She is taking it to France. A BMW Z3 with a dirty green roof is in the workshop at the same time as a cautionary comparison.

A BMW M3 convertible -- 12 to 15 years old, roof never professionally cleaned. Jet wash zigzag marks, grit and green growth throughout. Gary admits he really wants one, preferably in blue, and notes the £330 a year road tax as the only downside.

A Bentley convertible in for roof clean and reproof. Small holes have begun at the fold lines -- Gary repairs them, though warns the repair is not invisible. Nearby an Audi needed a full replacement roof at £1,800. For a Bentley, a new roof would be at least £10,000.
