I may be showing my age but my last convertible was a British Racing Green, Triumph Spitfire (late 60's vintage) and caring for the convertible top was easy. A quarter-bottle of Armor-All and the naugahyde looked like brand new (I am so glad we ended the senseless slaughter of naugas). Does anyone have an idea how best to clean and protect the TT Roadster's ragtop from UV?
