CARBON PRO's revolutionary technology is the first waterproofer that works as a 'spray on' membrane. The latest technology gives perfect adhesion on all flexible surfaces whilst allowing the material to breathe. The high performance CARBON PRO gives extended long-lasting protection against wetness and dirt for all materials. After the application (from a distance of 30cm) a resistant, breathable, net-like structure of polymer chains develops. Water drops roll off perfectly. Allow to dry, then polish smooth leather or roughen suede afterwards. Effective and long-lasting protection. Suitable for smooth leather, nubuck, suede, textile's and synthetics. We recommend the use of CARBON PRO on Really Wild's Spanish Boots, as well as on our leather and suede clothing to prolong durability.
