POR 15 paint is a good, hard moisture curing polyurethane. A Union Carbide paint rep told me about 20 years ago that the base material for all PU paints is made by 4 companies worldwide. The price was about the same for the raw material. Bottom line, if it is inexpensive, it doesn't have much expensive stuff in it. There is no such thing as cheap but good PU. I haven't checked, but I expect that if POR 15 has doubled in price, Pettit and Imron have too. Amazon has a gallon of POR 15 for $210 and Pettit 6980 Rustlok Steel Primer for $158. Pretty sure that is a major price hike for both. Pettit Trailercoat had a great reputation for boat trailers. 6980 is exactly the same thing as Trailercoat 6980. I checked that directly with Pettit. So, yes, there is a very similar alternative for 75% of the price.
Milkstone cleaner is very similar to a number of products sold for pretreating aluminum for conversion coatings. Same or similar phosphoric acid concentration, detergents and solvents all about the same. I read the SDS for Milk Stone remover. Used to look at paints and phosphate coatings sometimes as part of my job, so SDS reading is pretty routine for me. Cost, not the same by at least half. It is as Showcrop says a less expensive version of iron phosphate.
POR 15 Metal Prep contains some zinc salts that can produce a heavier zinc phosphate coating with more rust resistance. We are comparing good enough to better, but nothing major. I still use the POR stuff because I already have some. When that runs out I will probably pick up some Milkstone cleaner.

Today's Featured Article - The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange. In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and
