POR-15 VS Powder coating

I have seen it go both ways here in the Forums. Here is a chance to poll it out what do you think should be used on a freshly repaired and sandblasted frame during a shell of restoration.

Rustoleum primer & paint spray-gunned on. It is holding up well.

Powder coat

I really liked the idea of using a powder coat on the trailer frame... but after some consideration I have changed my mind! I looked into doing the POR-15 but this was just as expensive as the powder coat at $350+. So I was going to stick with my guns on the powder coat. That was until I received the frame back from the welder. This guy builds custom snowmobile trailers for a living. He is completing his dream trailer and he turned me on to the idea of using bed liner as a finish coat. I saw his and it looks good, I priced out having the frame done and it was only $250 or less. It comes in many colors and is very durable.
What is the problem with powder coat I find out is that it will not fill the pock marks left from rust and welding, this leaves exposed areas that are susceptible to rust.
I thought I would throw out that idea. It only adds 10-15 lbs to the total weight and is guaranteed for life. Pictures to come.

I like it, just be sure that the coating is not applied in the area where the axle mounts on.

Thumbs up POR-15 -vs- Powdercoat

I voted for POR-15

1. It can be applied very easily by anyone, anywhere: brush or spray.
2. It can be touched up readily after drilling holes, welding, etc.
3. It can be topcoated with any color after using a tie-coat primer.

My 2 cents

Have you never questioned those who travel? Have you paid no regard to their accounts- Job 21:29

Por 15 is better

I've used POR and Powder Coating on my old cars. POR (and epoxy primer) are better in that they will seal the fresh metal from the oxygen in air and thus prevent rust from forming. I powder coated many suspension parts on one car but after a year or so the parts had a light coat of rust under the powder coat. Also it would be easier to paint a frame as you would need a big oven for the frame.

It's POR 15 for me. It works, don't need any special tools and can be touched up as required if you need to drill a hole later. Have used it for a long time now and never a problem.

Less prep for POR-15. If you powdercoat, you have to sandblast it totally clean, then powdercoat if before rust can begin re-forming. With POR, you can apply over light rust.

Applied POR-15 w/ last coats going on after midnight, outside, using 17w CFL drop-light, at 38F temperature... finished surface looks every bit like factory fresh paint from FOMOCO or GM with no evidence of rust spots now after 8-10 weeks. I kept brush core damp with a few drops of their thinner and was amazed at how far the coverage stretched...

However, either the paint fumes or the POR-15 thinner gave me a heluva hungover type headache for the next day or two - don't use the POR-15 thinner on your face if you get splattered since it burns like mad fire!, Kerosene or lighter fluid will work just as well....

I used Rust Bullet. No need for spray guns or anything, I used a pan & roller.

Here in San Diego we have a local Co., Pro-Line Paints [619]231-2313, that does a lot of paint contracting with the navy. They developed a water based product. 801 Pro-line All Purpose Rust Conversion Primer. Application consists of wire brushing the loose rust and brushing the product on. It chemisally reacts with the rust and forms a black hard oxide. It does not have UV inhibitors and must be then covered with another type of paint of your choice. I used the 801 and then brushed a two part liner polyurethane over it on steel posts used for a palapa built about a hundred feet or so off the beach in Baja. It has been 2 1/2 years and two hurricanes now and it is holding up well. Something for you to consider.
