For best results, fabric surfaces to be treated with Nanolex Convertible Top Sealant must be spotlessly clean and completely dry before use. Working in a warm, dry place out of direct sunlight, Nanolex Convertible Top Sealant should be sprayed on liberally and then rubbed in well with gloved hands before being left to dry for half an hour. Once dry, a further application should be made to ensure that maximum protection is achieved. Any overspray on to adjacent surfaces should be wiped away immediately with a Nanolex Microfiber Buffing Towel. In order to get the best performance and quoted durability from the resulting finish, allow it to cure for a further 24 hours before using your car or exposing the treated surfaces to the elements.
