| + | **Rust prevention products are primarily advertised in hobbyist mags, not in periodicals read by professionals in the paint and body industry. | ||
| + | **The lack of rust preventive products in non-hobbyist industries does appear suspect. For example, why don't ships at sea use POR-15? | ||
| + | **The major paint manufacturers like Sherwin Williams, PPG, and DuPont don't produce a POR-15 like product. This is thought to be because they couldn't possibly warranty such a product. | ||
| + | **The fact that POR-15 is not used by manufacturers is also important. | ||

Put a handful of nuts and bolts in, chain, chainsaw blade, etc., and shake it around a bit to knock out the loose stuff. Not too aggressive -- you'll dent the tank. Then, clean with phosphoric acid. Pour it in, let it sit for up to an hour, then flush with water and baking soda to neutralize. Or, Eastwood has a kit for this: an acid to clean it, and then something to coat it with. However, some people say that the coating can clog up the fuel filter, or trash your OEM sending unit. The best way to do it is to take it out and get it re-tinned. | Put a handful of nuts and bolts in, chain, chainsaw blade, etc., and shake it around a bit to knock out the loose stuff.
