Rub 'n Restore colors and clear finishes are water-based acrylics and do not alter the feel of leather or vinyl. However, there are a few exceptions: Absorbent aniline leather with a warm velvety texture may slightly cool in feel after being refinished. The leather will continue to breathe and may remain absorbent, but it will be more fade and stain resistant. Worn areas or materials with a subtle nap like suede, nubuck or microfiber may stiffen as a result of being refinished / painted, and we discourage using our products on these materials.
