I've been very happy with Meguair's products and have used them for years on several cars and I love the shine/protection it gives. Last week I had a friend come over to wash/wax his car at my place since he lives in an apartment and introduced him to their Scratch-X for some marks/swirls he had on his paint and wheels and he was astounded. After we finished he asked me if anyone had considered using it as a cure for cancer The stuff is really incredible and for a readily available product at most auto parts stores, it works great!
