Rust-Oleum Tub and Tile Touch-Up repairs chips, scratches, dents and defects on porcelain, ceramic, fiberglass, acrylic cast iron and steel surfaces that are subject to water exposure. It is a washable, moisture- resistant finish that is suitable for use on tubs, tiles, sinks and toilets. This durable two-component epoxy acrylic provides a high gloss finish to make such surfaces look newer. Do not use on surfaces exposed to temperatures over 200° F such as stove tops, areas of constant high humidity and water immersion such as swimming pools, hot tubs, saunas or for use on galvanized steel or flexible plastic.
