I have been working on boats for over 40 yrs. and this polish is the best so far. It is not for heavily oxidized boats just for polishing boats that aren't bad and just cleaning them up back to a high gloss. One thing I have noticed about Meguirs and some other polishes and waxes is that the plastic on the containers cracks if you drop them. So just don't drop them. The product is top notch.
