The 12 oz Coping Paint Gray is specifically designed for use on aluminum coping in vinyl liner pool systems. This gray coating helps restore faded, oxidized, or weathered coping while offering protection against UV exposure, corrosion, and pool chemicals. Its quick-drying formula and easy spray application make it ideal for small touch-ups or professional refinishing jobs. With proper surface prep and multiple light coats, it delivers a clean, refreshed look along the pool's edge and helps extend the life of coping material.
