Rust Encapsulators

[doug73cs]

MarHyde, Wurth, Eastwood and Por-15 all feature a line of rust encapsulator treatments for surface rust. I'm considering using it only for surface rust in either hard to reach areas, inside of doors, rear quarter panels and floors before sound control treatment - places that sanding and grinding is a major pain and media blasting a global mess.

Anyone had any experience with them?

I've used the Eastwood product & POR-15. I've been pleased with both. POR-15 is more difficult to use & has shorter shelf life.

Metal ready followed by POR15 has worked great for me.

Used Por15 extensively 4 yrs ago during a full resto. Trunk, underbody etc. Need a respirator and good skin coverage. It's held up well.

Bought POR-15 products Marine Clean, then Metal Ready rust coverter. When rust was grounded out, cleaned and treated into oxide, covered it with fiberglas resin. Made lasting repairs that sanded an surfaced with little or no bondo..

I use Zerorust. Cheaper, more colors, and better UV resistance than POR

Thanks to all - seems like a good system to use on the light rust.

heres an area ive had extensive experience like gasoline, you will hear many claims about whose product last longer, etc. bottom line is that the chemical reaction to convert rust into an inert form is all the same. its what you do after making it inert that's worth researching. the cheapest of all products is called "Naval Jelly" and you can find it in just about every hardware store. looks pink, like thickened pepto bismol. spread it on, wait about 5-10 minutes, then spray it down with water. you will see the rust turn black. you can then treat it with some kind of spray epoxy, primer and then spray paint. mind you, I'm only talking about surface rust.

for structural rust, cut and weld. then treat with some kind of epoxy primer and then spray paint.

Goto your local Ace Hardware and buy yer'self a bottle of OSPHO. A friend of mine' dad works at the San Onofre nuclear power plant and told me that it's what they use. Highly rated and has never let them down. He swears by the stuff and has been there 25 Years.

I used it on my '02 as well.

I believe the OSPHO & naval jelly are both phosphoric acid products which convert the iron in steel to iron phosphate. Technically that's corrosion. Practically, it's good corrosion. The iron phosphate is resistant to combing with oxygen & producing rust.

I think a phosphate finish was & maybe still is used on some firearms.

Many years ago, I took a bunch of chemistry courses at a major,top tier university. I make every grade on could make A thru F. My knowledge of chemisty has become somewhat, ahem, rusty.
