Hey guys, I have a question. I have heard some of you using this product POR-15 and after checking out the website today, it sounds like the answer. My question is, which would be better for coating the underside of a box and cab, POR-15, a powder coat, or a rubberized coating? I don't like the idea of the rubber because I could imagine it chipping off and opening up exposing metal. I have been told that if it is done right, that won't happen. As for the powder coating, I had my core support and inner fenders done and they look amazing. I like the idea of having different colors available, but don't know about how you would limit it to just the underside. I was watching Musclecar a couple of weeks ago and they powder coated a primer on a whole car before they started to do the body work. Just asking what you prefer and any opinions. Thanks.
I used Por15 several times so far and I like it. It's expensive but covers well. So far after a couple years its done its job on rusty metal but I do recommend top coating it like they say. Also it dries flat which I didn't want.
I can vouch for por15... Just follow the instructions to the letter and make sure your surface is clean. Also.. It can be messy so rubber gloves and disposable brushes. I got my brushes and stuff from harbor freight cause I knew it would be one use and throw away. It was something like 20 for $2 or some crap. I ended up using them all after a few months of painting parts. Here are some pics of how it looks dry.
And here is a before and after of the cab floor...

Por15
Hope this helps... The stuff is sort of glossy (it has a natural leveling effect) and really dark so it doesnt take the greatest pics.
You will like it. My cab floor will be sitting on the ground somewhere after the rest of the truck has rusted to dust.
Raptor and Hippo Bedliners are an option. They are spray on bed liners and they can be tinted to what ever color you want. I would warn you that its a good idea to shoot either basecoat or single stage paint on the surface your going to spray the bed liner on so you dont get a streaked apperance where you shoot the bed liner. Its tough stuff and is hard to chip off. Ive had pretty good luck with it.
On my truck I'm going POR-15 then a roll on bed liner ( Durabak ) .
I don't like just using undercoating. Some of the rustiest trucks I've owned have been undercoated.
My experience with undercoating is it seems to stay soft and can be scraped or scratched off especially in hot greasy environments. Might as well go four wheeling on some fresh asphalt as it sticks better.
