The Firestone QuickScrubber Kit provides the necessary tools required for the application of QuickPrime Plus Primer. When making a seam between two pieces of liner, it is extremely important to do it right the first time. The kit contains 30 scrub pads and 4 holders designed specifically for the process. The scrub pads will prepare the liner while the holders will make the application process simple and easy.
