No protective coating is maintenance free, nor do any last forever, that's why we created the EXPRESS CARE KIT. This all-in-one Kit is a compact version of the CONSUMER MAINTENANCE KIT (CMK). The ECK helps make your routine maintenance much easier, even if you've neglected it for a while. Each Kit comes with: four Revitalizer NanoPax, two Restoration Powder Packets, a nylon cleaning puff, a scrubber pad, and a microfiber towel. Each single Revitalizer NanoPax is designed to treat up to approximately 14 square feet.
