Re: What do I coat my frame with?
Southern Polyurethanes (SPI) black epoxy is what I'll be using.

Re: What do I coat my frame with?
I used Rustoleum on mine. Preped the frame real good, primed, then sprayed a few coats of paint. The reason I went with Rustoleum is it is pretty durable and if it does chip it is easy to fix.

Re: What do I coat my frame with?
The powder coat has held up great. No regrets here.

Re: What do I coat my frame with?
It's somewhat a myth powder coat is expensive, but it's sure a lot more $ than a six pack of spray bombs.
I had my frame, cross members, axle and another dozen parts PCd for $1100. They blast and prep everything just right with awesome results. As others have said before me, I wouldn't PC a driver, because paint can be touched up to match or close. I think it also depends on the condition of the frame. If it's rusted I'd bypass any thought of powder coat and run with Master Series. I doubt anything is more durable, their primer is TOUGH. For what it's worth, I did spray bomb my frame with Rustoleum with nice results. Lasted 20 years plus, but it's dry here and the truck sat in the garage. IMO, if you've gone to the trouble of stripping the truck down, I'd forget about spray bombs.

Re: What do I coat my frame with?
Check out the Eastwood 2K spray paint in cans. You press a button on the bottom of can to release the catalyst, shake and spray. I like the way it sprays, but be advised there isn't a lot of paint in those cans.

Re: What do I coat my frame with?
I brushed/rolled 3-4 coats of rustbullet on mine. I was in a rush to get all the coats on while still tacky so I ended up finishing at 2am. My prep was spot on, the frame was perfect. My regret was not spraying it. Next time I'll spray or maybe just send it out to be powder coated.

Re: What do I coat my frame with?
Its all about how well you prep, prep and prep some more. Also temperature and methods you have available to apply. Just did a bunch of blasted parts with EGC epoxy primer and some eurethane topcoat. Came out great, but cost me about $200 ($100 gallon primer and $100 pint of black) in materials bought from a local automotive paint supply house. To do a whole frame like this, ouch and better have good ventilation. I previously pressure washed, wire wheeled, scraped the frame and applied Eastwoods paint over rust products. Looked good at the time, but 5 years later needs to be redone and this was on a weekend, fair weather driver. Personally, if you are going down to the bare frame, powdercoat it, or epoxy and a topcoat. Long term goal for me, find another frame and go powdercoat.

Re: What do I coat my frame with?
Agree w/previous comments, it's all about prep.
I'm a POR-15 fan, it hasn't let me down. Media blasted + painted assembled frame about 15 years ago. Frame even sat out on Oregon farm under a single thin blue tarp cover. It's a little dull (satin) from the weather/elements) today but still sold, no peeling, chipping, resists all kinds of chemicals. Still beat on it during suspension overhaul. Stuff is tough as nails!

Re: What do I coat my frame with?
To do por15 correctly expect to spend some TIME. I did all the reading I could. I had used por15 in the past but it didn’t hold up that well. It’s all in the prep.
This time I did (as was recommended): 1. Sand blast. Not required but makes life easier. 2. Degreaser. Unnecessary but came with the prep kit so I used. 3. Etch and prep. It’s phosphoric acid that converts the rust and etches the metal to promote the por to adhere. There are many other phosphoric acid products you can buy from the local hardware store. Krud Kutter is one. 4. Must be completely dry before then the first coat of por15 applied. Light coat is best. 5. Wait until the first coat is “finger drag” dry. Usually and hour or two. Then applied 2nd coat. It’s important to not let it dry fully or nothing really sticks to a fully cured por15 6. After finger drag dry 2nd coat apply a dusting of por15 tie or bond coat primer. 7. Now you can wait as long as you want to apply the 2nd coat of primer. Let that primer dry and you can finish it off with whatever top coat you want because now anything pretty much will adhere to the primer coat. 8. I used Eastwood chassis black. It was tricky for me to get the correct coverage. A little to heavy and you get shiny spots. A little too light and it’s really dull. It was the most time consuming paint I’ve ever done but I can say it’s probably the most durable too. I didn’t know all this going into it and probably wouldn’t have gone this route because of the time involved. Most important things to remember: you must not let the por15 dry completely if you are going on top of it with something. Almost everything put on top of it will scratch off with a fingernail and that’s VERY disappointing. You can always scuff sand the cured por 15 to help but who wants to do that? Por15 left open to exposure will get a chalky finish. It won’t keep that super high gloss shine. Exposed to sun only increases that effect. First pic is after blasting then etching. Bare metal but looks white. Second pic is por15 Third is bond coat primer. Last edited by Slowguy; 01-01-2019 at 12:53 PM. |
