This paint like stuff or thin like water we are talking about here? Went to an Orscheln's and got some Agway brand rust sealing paint, just black. Similar to POR 15 but cheaper. Came in Qt, for about $20, not real cheap. Brushed on like paint, little think, shined like crazy and dried very hard. It almost acts like a Glue on jointed areas, so watch coating them. It does say if using outside and in sunlight it will haze and dull. They recommend top coat of paint over it. Seems odd, but I did paint over mine again. I have also used POR 15 and it works same way. Have to order it on-line, expensive. Both of these coatings said not to get into the rim on can, or if sealed, won't be able to open again!! I KNOW that is true for the Por 15, was more careful with the other. There was coatings offered in car magazines that I have used and it came in more colors. Not recalling name now. Zero Rust I think it is. It is similar to the others mentioned, but is more paint like, not quite as tough, and says you don't have to top-coat. I've used that in Red and Black in past. I never keep things long enough to know the long term stand up on these, so can't really tell how long any will last, heh!
