Easy to remove, removes readily with CRC® Lectra Clean or CRC® Brakleen. Low surface tension and an affinity for metal, ensures that a continuous film of product will blanket every part of the surface. Protects aluminum (anodized or mill) and copper from plaster burn and concrete burn, prevents finger printing, the corrosive action of acids and oils left by human handling. 300 g Aerosol Can, Blue to Green
