I use Picklex 20, or an equivalent. I use it as a rust preventative. It will protect the metal for months, as long as it is dry. It will not repel water, and should not be washed off. I do not use rust converters, as I like to remove all rust first, either by sandblasting or a wire brush on an angle grinder, etc. Others have different opinions, I have no argument. In other words, I use them to prevent rust until painting. One exception, the preventatives I use will also take care of flash rust, or rust deep in the pores of cast that is next to impossible to remove. But, I do not use them over heavy rust, not saying that you can't do that, I prefer not to. --Use an epoxy primer over it, not an etch primer, as you may wind up with too much acid. There is another product called "Must for Rust" sold by Home Depot, that I am currently using. It appears to work like Picklex, but I have not had much experience with it. Of course anyone reading this post is more than welcome to give their opinions.
