I just got done wire wheeling my frame for my 76 Highboy. Now I am ready to paint it 1st I am going to Por-15 then what should I use to go over the top of it. I got the body off so it will be easy to get done now and I dont want to have to slobber more paint on it in 5 years. I am afriad of regular paint peeling and falling off when I put the pressure washer to it or when its gets muddy and the mud dries and falls off I am worried itll take the paint as well. What have you guys done or suggest. This will not be a show truck, a truck that will be used for hunting and getting muddy so what will hold up the best.
Many folks use POR-15; but I've used Rustoluem Hammer paint. I shoot 3 parts paint & 1 part thinner from a quart can; Recently did a 74 Highboy chassis on a 76 body; its in my gallery.
there's numerous good quality paint and i feel for the price Hammer does a great job. I have used rattle cans to touch up as needed once sprayed and for touch up.
I'm wire wheeling my 74 high boy right now (and using strip discs quite a bit), and have applied some POR-15. When I'm done with POR-15, I haven't decided yet, but think I will get some brush-on undercoating and cover the whole underside.
The combination of POR-15 and undercoating has to be bulletproof. I've scraped undercoating off of a few 40 year old muscle cars with mild to moderate rust, and when I got the undercoating off, it was nice virgin metal underneath. Imagine how great it would be if it had also been POR-15'ed. I'm the biggest fan of POR-15 and have used it quite a bit. Cheers.
I wheeled my '76 frame and primed it with Rustoleum's Rusty-Metal Primer and put on two coats of Rustoleum satin-black and it works and looks good. Just don't get too close to it with a power-washer because some of the top-coat can blow off.
I've used POR15. If you are top coating it, you have to use a POR tie in product. If you are using it on the frame, whey do you need to topcoat it? If its on the frame, it wont be getting any UV rays.
I agree with hp246, why are you worried about top coating the frame?
But, POR15 has their own top coat paints so just put one of those on and you should be golden.
I know POR-15 wants you to use their own special topcoat product, but regular undercoating won't have a problem adhering, not when it's a rubbery layer 1/4" thick. Additional benefits of undercoating are sound deadening, and putting a physical barrier between road chemicals and your POR-15'ed metal.
NOT trying to highjack this thread but any word on chassis saver? i plan on having my frame sprayed with it only because my brother inlaw knows a guy that will do it cheap. he works for a local trucking company and sprays all their tractors and trailer frames with it.

Primer attracts moisture over a long period of time if not topcoated. I'm not sure how POR15 or Rustoleum primer holds up, but I'd rather play it safe and topcoat it anyway.
Cleaning the frame (body-on) is such a nasty pain in the butt - I have no ambition to do it twice.

POR 15 is not a primer (although they do offer primers). I believe it comes in black, gray and clear. Moisture actually makes the POR 15 harder. I had a can stuck to my pole barn floor for 3 years.
You can top coat POR 15, but you need to use POR's system to do so. If you don't it is just a waste of money. Been there, done that, got it all over the t-shirt to prove it. If you don't use their system, you will have a mess. I don't know if the undercoat will stick or not. You may want to go to their web site or contact their tech support guys.
There are some other products on the market that guys swear buy. I think one is available through Eastwood. You might want to check with them. I tried Rustoleum. In my opinion, it is worthless on this application. Within 6 months it was peeling off my frame. I had to media blast the frame a second time to get it off. I've had the POR 15 on for about 3 years now with no problem.
I believe Rust Bullet is another product that is used for similar purpose. I've never used it, but seen good reviews on it from other web sites. POR15 is not advertised as an undercoat.
