Actually it’s white in the bottle, goes on white, starts to turn purple as it begins to react with the metal, then turns a dark black after it converts the rust and dries.

I appreciate the input Donovan. I'm also not a big fan of putting water on a bare metal surface either, but I usually don't get any flash rust, if I do I just hit it with a red scotchbrite or a DA very quickly before wax and grease remover. From what I gather, P Auto has a much wider range and selection of products than Horror Fraught. Nobody seems to carry Plastikote stuff locally that I know of (maybe someone local here might) and you can't seem to buy it on Amazon or eBay. I think I'm gonna stick to Rust Mort for now. This doesn't have to be beautiful, it is just a firewall, not a roof or a hood, but I think I'm gonna try to do it body color and I'd hate to have rust bubbling up under the paint in a year or two.
To be honest, I think that’s probably your best bet if you can’t get the PlastiKote stuff or anything similar locally. Stick with what you know, and apply the KISS principle. I know this isn’t your first rodeo and you know what you’re doing, so I’m not concerned in the least that you’re not going to properly prep the surface after using the RustMort and rinsing it.
You know what needs to be done, you got this man!
Thanks for the vote of confidence! It's been several years now since I was doing this for a paycheck, so I've been second guessing myself a little. Technology moves so fast with this stuff, I want to make sure there isn't something better out there that I should be using instead.
I concur,
I've used Por 15's paint and rust preventative product for years on my different rusted cars. Used correctly and with the metal ready primer, it will last forever
Never have had any issues since. Por 15 will encapsulate the areas that you have prepped, and it's self leveling, which means add a few coats, and the pitted rust holes will fill in and level out. Not the cheapest, but found it to be the most effective. You can see some of my past por 15 use here....
My vehicle restos...
So yeah....., it has worked well for me. I recently redid the Rally rims on my el camino with black epoxy paint, then a clear epoxy coat with the por 15 paints.
Back in the 70's we painted Navy ships and rusty military hangers with government red lead, which worked very well. Years ago I was wanting some for my Camino's rusty floorboards. Not feeling up to the intrigue of finding some or making it up , all I did was chip the heavy rust scale away, and give it a quick surface grind with a drill mounted sanding disk, followed by a wipe with a rag and thinner. While I did not expect results comparable to red lead, I took a leap of faith and bought a gallon of Rustoleum Rusty Metal Primer. The first full brush coat penetrated the surface rust, and the second full brush coat sealed the deal, by stopping oxygen absorption. The point is, no rust has reappeared after years of my doing this, and the paint looks as good as when applied, except for worn off areas, because I don't have carpets or mats. If I had top coated it with a compatible Rustoleum finish coat ,after the two primer coats, it would be even more impervious to re rusting , but I haven't even had to do this. I might, as it comes in assorted colors and sheens. It is important to wash all surfaces clean of salt deposits, and you must apply two full coats, with adequate drying time in between. I prefer brushing it on. I think two primer coats, alone, seal against rust better than one primer coat and a finish coat of enamel, which is the usual procedure.

I too have used the Plasticote and the Loctite product. I don't have a bunch of rust showing through after one year, a good sign. Pretty sure they are identical, look and smell the exact same. Use what works and is available.
Keep in mind that most rust converters will cause flash rust on clean metal as they are only meant for rusty metal.
