Best option for underbody rust?
Some of it is bad enough to where it is starting to flake off and some is really just bubbled but not terrible.
I want to do something to go ahead and take care of it before I start driving it just to make sure it doesn't get too much worse for awhile- but after looking at Eastwood's website I have no idea what I should use.
It has to be something I can apply upside down (since the bed is still on the truck), and I'd like it if it doesn't require a ton of prep. I was going to do POR 15 but then I saw that you're supposed to use their marine clean, THEN etch the metal and THEN apply the POR 15...I don't really want to do all that prep or have $100 tied up in doing these few spots of rust. I didn't spend a lot on this truck and it has 175K on it so it's not like I'm going to be keeping it forever, but I don't want the bed to rust out either.
Recommendations? I was looking at Eastwood's Rust Encapsulator but I've seen mixed reviews on it.



I'm not a fan of the quick fix Band-Aid products; it's hard for me to warranty such repairs as they are typically just as quick to re-appear. So in looking for a more permanent repair, we went with the new bed floor (still available at your local dealer) so it should be mostly spot/plug welds to repair. We're still waiting on a couple crossmembers, but prepped what we had so far and sprayed with SPI epoxy primer...





Once installed, the owner plans on a spray in bedliner, so no topcoat on the SPI epoxy will be required..
Cost is relative to how long you want the job to last---certainly there are cheaper ways to go than POR-15. I hate doing something twice so tend to opt for the better quality materials.
