I really didn’t know what to expect with this product from the description, but I ordered it as the manufacturer recommended its use prior to painting. Upon receiving it and reading the product composition and application instructions, I see that the chemistry involved is quite sound. It is a phosphate/zinc composition that forms an iron phosphate passivation layer on the metal and the zinc compound then provides (albeit thin) a galvanized surface layer. Worked very well when used as directed. It is important to keep the surface wet for 20 minutes as they direct so the chemical reactions can take place.

Rust conversion products claim to change the chemical nature of rust and convert it to a more stable element that won’t rust again. History of the failure of these products is well documented; most simply don’t work for more than a few months at best, and they are subject to the same chipping and cracking that occurs with ordinary rust coatings. POR-15 works because it chemically bonds to rusted metal and forms a rock- hard, non-porous coating that won’t crack, chip, or peel. It keeps moisture away from metal with a coating that is strengthened by continued exposure to moisture. See more information at https://por15.com/.
