This Quart (32 oz) kit will clean and restore about 250 square feet of metal or about 750 linear feet of 3" window frames. Everbrite will restore the color and luster of faded aluminum, window frames, pool cages, lanai's, patio furniture, yard art, painted metal ... you name it. All anodized aluminum, powdercoated, or painted surfaces will fade and chalk over time from sun damage. Once they are cleaned, Everbrite will restore the finish and protect the metal from fading again for years. Plus, you can reapply it easily to continue protection indefinitely.
