Frame Prep for POR 15 coating

[Vindictus]

Very good!

When it comes to fighting rust, I'm kind of a belt-and-suspenders guy.

I bought a cheap $80.00 media blaster to remove the scaley rust. The blaster will go faster and get into the corners where the wire brush won't reach.

POR 15 works wonders but it will not penetrate the thicker stuff. They've got a product to apply before you paint.

Also POR 15 is only a primer. I bought a couple cans of Rustoleum Rust Encapsulator to go over the top. Spray paints alone won't last long on the frame. They need to be sealed too. Spray polyurethane or urethane will seal and last for a few years.

And if you want your exhaust system to last, It might be worth it to give it a couple coats of Rustoleum high temperature paint. Most spray ceramic coatings do not work as well.

Good luck!

I have a decent sand blaster but my big compressor is not running and I killed one of my small compressor blasting a bike frame for a friend a few weeks ago. Up grading the service on my house Friday. Then I can look at putting power in garage

I was going to topcoat it like you said but the can of tremclad I thought was grey is canary yellow. So I'm stuck sanding it before I topcoat it.

You will get a good bond anyway. i'm pretty sure

I got it topcoated over the weekend. Picked up a gallon of Amor Coat rust paint and gave it 3 coats.
Started like this and ended with this
I started puttingit back together tonight. Got the trailor hitch back on. The carbon fuel box thingy back in place and the wire harness pulled back in place.
Got to dark for any pic's

Digging up an old post.... For those of you who have used POR 15 on your ranger frame, how much did it take? I am going to do my son's frame but just what I can reach from a lift. Wont be removing the bed or cab. A freind of mine built a 66 Chevelle over 20 years ago and the stuff held up great. About 5 years later (15 years ago) I used it on my 86 K20 frame and it has done great. I just don't remember what size container I bought.

It took me two days to paint the Ranger frame. I put on two coats. I'm glad I did. There were spots I missed on the first pass. POR 15 is just a primer. So I spent a third day with some spray cans. If you have the time, it's better to remove the bed.

 

[flyin-lowe]

What size cam did it take?

 

[Lefty]

If I remember correctly, it took about a quart and a half. I should have used one or two of those six packs, each of which is like a half pint.

I would imagine that one six pack would do if you choose not to remove the bed and if you apply just one coat.

Thanks, last frame I did was a full size 3/4 ton Chevy and that was frame and cab off about 20 years ago. This one will just be what I can get with the bed on and what I can get to with a lift. I might buy one of the kits with the degreaser and metal prep and then an extra quart. I think those kits come with a pint jar but not certain.

If you're not doing everything at once buy the smaller cans. I've never ussed it, but everything I've read is that once a can is open it's done. If you buy a gallon can to do a frame a section at a time, and you'll be buying another can for the next section. Buying a bunch of small cans might seem more expensive up front, but in the long run it comes out cheaper with less waste product. Again, I've never used it, but I've read the same story several times.

 

[Lefty]

Yes, once you open a can, this stuff sets up pretty quick.

After I open the can I used shrink with a rubber band to re seal. Pick off the layer of crust on top.
I bough quart cans.

I've used POR 15 on a '79 Vette and my 2001 Mazda B3000 - from the Cab back. This stuff does seem to cover a lot of area. I've used the Six Pack (Xoz. cans) and Quart cans. If I have not used the whole can, I use MEK to clean the top sealing flange and flange on the can.

Before closing the can, I put a doubled up piece of plastic wrap over the can and install the top. It seems to work pretty well to keep the left over paint usable later. Have not kept track of time between uses, but think it's kept good for 2 years (the Vette has been a longgggggg term project).

Had to change the B3000's Fuel Pump. With the bed raised figured I'd touch up the frame and underside of the bed.Used a Quart can of POR 15 that had been stored with the wrap for about two years. It had a film which was easy to remove, mixed it and applied with no issues.

Wanted to apply Top Coat to the PORd surfaces and had 3/4 of a quart sealed the same way. Probably last used it the same time as the open POR 15 can, but after opening it found it was commpletely set up.

I've heard some folks freeze the unused portion and have good luck from setting up.

saw a video once of filling the opened can with propane to expel the oxygen during sealing, the can. no long term follow-up though.
