I haven't used the rust converter, but I have used both Rust Encapsulator and Por-15. I personally think each has its place.

The rust encapsulator provides a thicker, softer coating than the por-15, which is thinner, and rock-hard. I use the Por-15 on areas that I feel will take more abuse, like the frame, axles, control arms, etc.

I've used the rust encapsulator on areas like inside support pillars, inner cowl, inside the doors, etc.

The rust encapsulator has one major advantage on por-15 in that you can store it after opening. You can buy a quart of encapsulator and use a bit here, and bit there. Por-15 is pretty much all-at-once. storage options after the can is open are minimal and limited.

I like them both.
