When it comes to stopping rust, which is better? Eastwood Rust Encapsulator or POR-15? Well after doing my own research I think POR-15 has to win my vote. I've checked many forums, such as Corvette Forum and LS1Tech, they both seem to favor POR-15 as the winner out of the two. Great thing about POR-15 is it's really tacky stuff, it goes on real easy and you don't really need any prep. I do however suggest using their three step program, but the company claims you can spray it right on the rust.

The Rust Encapsulator still is a great alternative though, I haven't read any negative reviews yet. It's easy to use just like POR-15, just remove any loose rust, then just spray it on. If you want a really good job done, use Eastwood's Rust Converter first, then use the Rust Encapsulator last. Eastwood claims it has twice the corrosion resistance now. Rust Rncapsulator is now good up to 500 hours on a salt test. It also has a fast curing time, great penetrating properties, and is epoxy fortified.

But let you do your own decision making. For all I know, maybe Eastwood's Rust Encapsulator is better. I'm going to try out POR-15 first though, it's getting the most hype and has been advertised on My Classic Car with Dennis Gage.

This is the three step program, first use the Rust Converter which is gray, then use the Rust Encapsulator which is black.
