I was thinking I would go with POR-15 for the underside, floors, trunk, etc. but since I have very little rust, the consensus seems to be that bed liner material is better.

My question is, since POR is great over surface rust, should I paint those areas with POR first, then bed liner material, or will the bed liner material be good enough on its own? Also, where have you purchased the material, regular parts house?

I'm sure I'll have more questions on the issue, so please be patient with me.

 

At a min. get some rust converter and brush or spray it on, wire brush it, clean it then spray on the bedliner coating. POR-15 is funny. I am pretty sure you have to use their stuff to top coat with. Or you can go with Eastwood's Rust Encapsulator and top coat with the bedliner spray. POR-15 and rust encapsulator is both very good stuff.

 

Thanks, I'll check out the Eastwood stuff. But is it like POR where if the surface has zero rust it won't adhere well?

 

I went with Chassis Saver, which I got from my automotive paint store. Have not heard many people talk about this stuff, but I've had it on for nearly 2 years now with excellent results.

 

OK, follow up question, how much of the Eastwood Rust Encapsulator do I need for a '66, doing underside, engine compartment and interior? They have a "full frame and suspension kit" that appears to have 3 cans each of encapsulator and paint, and 2 pints (?) of converter (part A and part B have to be mixed). Will this do it? I'm thinking 3 cans of encapsulator is a bit too little......

All opinions welcome.

 

I did my underside and interior with 2 quarts and a couple spray cans. I think the whole car could be done with say 3 quarts and a couple spray cans for the tight areas. This stuff is as good as POR-15. POR-15 dries very hard but RE is easier to use and prevents rust as well as POR-15. I did not top coat my RE on the underside. I still had 90% or more of the original red oxide, just added the RE for extra reassurance. You may want to get a few more spray cans to spray your engine bay. The brush on does self level some but is not at smooth as the spray. And to answer your ? on the adhering issue, yes, RE adheres to rust very well and to prepared metal almost as good. Once this stuff dries and cures, it is pretty hard. I did my underside in red and interior in black.

 

So in the engine bay, you don't need to prep it, except for the dirt? You can just put that stuff over the metal (in other words, no sanding needed?)

 

Wash off the dirt knock off any loose rust.

 

It all depends on how smooth you want the engine bay to look. I used a wire brush first with some mineral spirits then I sanded it pretty smooth with some 220 grit. Turned out pretty smooth. I POR-15ed it then top coated with satin black.
