I've started work on the 93 Mustang I got from my Son Don and it is super clean, even underneath. I want to keep it that way for a long time and am looking for the best undercoating I can brush on the undersides of the entire car.

About 10 years ago I undercoated the Capri Don now has with a product I can't find any more. I bought it at West Marine when I worked there and it was one product but they packaged it in two different forms. One was called "Trailer Coat" and was used to paint boat trailers, and the other one was called something like "Underwater Metal Primer" as I recall. It was urethane, silver in color, and you didn't want to get it on your skin. I laid under the Capri slopping it on, getting it all over me, then I tried to clean up with everything in the shop..........nothing touched it, so for 3 weeks I had silver splotches all over me, from head to toe. I was the butt of a lot of jokes at work those 3 weeks. BTW, that coating still looks like the day I put it on the bottom of his Capri.

So, what is the current hot product that will go over the factory painted surfaces on the underside of a car? I see POR 15 products, but they say rusty metal, which I don't have.
