All Donkervoort models, except the GTO, have a 100% pure cotton back mounting tape to prevent the bonnet from sliding and protect your paint. I receive many questions what to use. The exact product which the Donkervoort factory is using since the early days of Donkervoort production, is race bycyle tape! Your local bicycle store can order it for you. Attractively priced per box. It is from the French manufacturer Velox and called Tressorex 85. Dutch option for ordering here.
Just renew annually. It makes your car look much better!
