using spray-on bed liner to coat frame

[Slats]

Has anyone used spray-on bed liner as an alternative to POR-15? The guy I took my frame to for sandblasting today said he has used it on car frames and prefers it to POR-15.

If you're sandblasting the frame por15 isn't necessary since the rust is gone. A good primer and several coats of sprayed on frame paint is good. Por15 makes a frame paint you can use. The normal por15 is really for painting over rust.
What kind of bedliner spray. There are lots of different ones. Are you talking about the rustoleum bed liner stuff, or something like sprayed on poly plastic, or rhino liner spray?

[Slats]

Good question. I'll have to ask the sandblast guy which kind.

Here on the coast, it's not unusual to see pickups and especially Jeep Wrangler's painted with the Rino/Linex spray liner. Good for slowing down corrosion. Sure beats waxing!

i used bed liner on my frame. pack mentality is that por 15 is the only option but sometimes you have to use your own judgement. A 2 part epoxy bed liner will outlast any paint and i found it was the same price as the por 15. only difference is the textured look when you are done.

I have used a product made by reRubber on the frame of our Avion. It is a water-based liner that has ground-up rubber powder in it. It cleans up with water, but when it dries it is tough! The only place I know to get it is from the manufacturer in Californina.

Otherwise. I would think RhinoLiner would be a good choice.

The Rino/Linex stuff is really durable. I changed the bumpers on my TV for Iron Bulls (made of 3/16" steel plate - no bends, all welded together). They are coated with Linex and it doesn't chip or wear off.

I will be having mine powder coated after sandblasted.
I am doing a body off this winter and my buddy has a large powder coating bizness.
This way in one location they blast and move to powder booth and it never even has a chance for moisture in the air to hit it.
For those unaware powder coat is sprayed on dry and baked to flow out. This is how steel wheels are treated when manufactured.

POR15 means Paint Over Rust and does not need much prep unless there is a lot of grease. On a trailer, you usually don't have much grease but a lot of rust. Bed liner is overkill and heavy. If you sand blast, then use conventional paint.

A good two part liner over well prepared surface is very durable. It will take a lot to cover a frame well.

Two, three, or four gallons or more?

It wont be cheap.

On the other hand a gallon of black industrial Imron will set you back about $120 with activator, and it is more than durable enough to last a really, really, long time. (And it looks and covers great)

Black implement paint from Tractor Supply will do a great job on properly prepped metal. I have a utility trailer I built out of a 1976 boat trailer. I painted it in 1998 with implement paint. It sits outside year round. It has not rusted.

I would think its serious overkill. Any conventional exterior paint for covering metal should work fine, especially if its sandblasted and then primed correctly. If you think about it, the frame should stay mostly dry during its entire life. Parts of it may get wet from spray from the road, but should dry out quickly enough. Even if sections flash rust, they reach a state of stasis and there isnt much further oxidation. Where problems arise is when the frame stays consistently wet from leaks or when wet insulation stays in contact.

But if its what you want to do, then go for it. Show us the pix when you are done.

I removed all heavy rust from my 81' CJ-7 Jeep tub, and applied several light coats of POR-15. Very high quality product. The person that wants a frame off, lacks the personality trait required to paint over rust. Or so I would hope. Remove heavy rust, POR-15 and feel good about it. It's a great product. Just be sure to etch first.

There is some stuff out there called Aluthane and it is similar to POR15 but has aluminum in it which will help retard rust. I have used the stuff and it works well. You need a couple of coats of it though.

Good suggestion. But when I got to Tractor Supply, I saw all those other colors - JD Green, AC Red, IH Yellow and, the one that won my heart, Ford New Holland Blue.

I know, I know, no one will ever see it, except for perhaps the door step and, dare I be so bold, the bumper.
