Looking for product recommendations for painting the frame
 

I am about ready to restore the frame of my '72 GMC. I am considering POR-15, Rust Bullet, Eastwoods Chassis Black, and good old Black epoxy primer.

I am looking for product recommendations. Please share success stories for any products you are happy with and how they have weathered over time.

Thanks folks

Por 15 works good but follow the directions exactly or it will not work well. Finicky but you can brush it on and it looks good. I did the entire inside of my 66 fastback with this stuff and inside the quarters and all. Works good.

Get Eastwoods rust encapsulator. I read a magazine test that put it ahead of Por-15 for ease of application, durability, and UV resistance.

I've used Por-15 and been happy with it, but it's not fun to work with.

I'm down to two methods:

1. Eastwoods Rust Encapsulator with Extreme Chassis Coat Gloss Black topcoat.

2. POR15 with Extreme Chassis Gloss Blk applied within 3-5 hours when the POR15 gets tacky, but not yet dry. Then the Chassis Blk will stick without scuffing the POR15 and will provide the UV protection that POR15 needs.

Rust Encapsulator is easier to apply, by far. The POR15 probably provides more film strength, which is why I use it on axles where pebbles will try to chip the finish. Regular Chassis Coat sucks compared to Extreme Chassis Coat.

I powdercoated mine and was cheaper than painting it. It I was going to paint it I would use the same paint I would paint the outside of the truck with.

I used chassis black gloss on my frame. Couldn't have been easier to apply and looks good. The only place I had any rust was my rearend so thats the only spot I used the rust encapsulater but that was really easy also and once the chassis black went on it looked just like the rest of the frame.

Du Voe (not sure of the spelling) Coatings semi gloss 2 part urethane finish. Have done 2 chassis` and they come out beautiful. Has just the right amount of sheen. Restored a chassis about 5 years ago with por 15 and it came out terrible. Drips and runs and difficult to spray. Stay away from it.

I sandblasted my frame, Por 15 then top coated it. It turned out great. The Por 15 even applied with a brush flows out like it was sprayed.



Please read the Sticky message "What the hell happened" on the Paint & BODY forum before using anything. Por 15 and other products can pose cronic health risks.

That looks great!! I really like it. Nice trailer.

I used Por15 on mine after sandblasting. Applied it with a brush. Looks great but is a pain to clean up if you get it on anything else.

i heard of some on using Line-X spray in bedliner on there frame. It is some new stuff that is thinner than regular bedliner and is rubberized so it resists moisture. also if you dent it, it won't chip it flexes.

I used Eastwoods EXTREME chassis black satin and the recommended primer, so far, I am totally impressed -and- it can be recoated later without too much prework.

I brushed Zero Rust on to my frame, and I'm quite happy with it!

Its a softer coating, so if you hit it with something, it doesn't chip, and is very easily re-coated for touchups. Also FAR safter to apply than POR-15

I didn't spend a pheonominal amount of time on prep. I just went over everything with the angle grinder and in some places with the sand blaster, and any of the old coating that wouldn't come off, I simply coated over-top (thats what some of the rough stuff on the pass side rail is).

You can see further back on the driver's side what I was coating over-top.

Its been several months, and there is no indication of anything lifting, or peeling off. Infact, if the coating gets wet, the water just beads on it, and sits there for days until I wipe it off (too cold now for water to easily evaporate)

I am going to try Rust Doctor + Grease Doctor on the back half of the frame and underside of the bed. I have used POR15 before with a 50-50 opinion. Since it is available in my area I like the idea of powder coating though have not priced it. The next truck will be sandblasted and powdercoated.

Question: I see people saying they sandblast the frame and paint it with POR15. This I don't understand why sandblast and use a rust bonding paint. POR stands for Paint On Rust. Does POR15, Eastwood, or any of the other brands prevent rust from forming with rust inhibitors? Just a question and not a judgement.

Smoother finish.

i'm not afraid to paint over the rust but what i've found with most rust products by whoever is that you get your peeling and blisters from the areas that have remnants of the original paint the more prep work the better the final finish and i've got a blaster so why not use it

After I got out of the military (100 years ago) I worked as a sandblaster so I can understand the reason for the clean metal. What I don't understand is the use of expensive paint like POR15 and the likes when you have already removed the rust. Unless these paints have rust inhibitors to prevent rust it seems unnecessary to use them after sandblasting the frame. Wouldn't sandblasting, prime and paint or powdercoat be as effective?

I agree!!

It's hard to say what the best product would be for this situation with out knowing all the details.

What's the intended use of the truck after it's complete? Working truck, off roading, show truck, daily driver weekend cruiser?

What kind of budget do you have to work with?

Are you doing all the work yourself? If so what equipment do you have available? Sandblaster, spay equipment, safety equipment, ect...

I sprayed mine with dp90 epoxy primer.It was sandblasted first and it turned out the satin black that I was looking for.Everything I have read about the epoxy primers has been good as far as durability.I also did my utility trailer with the same epoxy primer and it has been sitting outside in the rain,snow,sun,you name it,for four years now and it still looks like the day I painted it.If you want a high gloss tho this is not the way to go but I would still use it as a base.

I just finished reading it. I will definitely be wearing a respirator whatever I end up using.

Using POR15 on a sandblasted metal will be smooth, as mentioned, but POR15 also sticks well to metal with "tooth." And POR15 has a film strength worth considering, whether being used over rust or blasted metal.

I agree,,,,,,,,,,,,,,,,,,,,, :(

powder coating is real real nice about $500worth/ getting nice epoxey primer and finish coat is also real real nice ,quart of primer,quart of top coat reducers catalst thinners etc maybe $150-$200//using the real expensive POR 15 paint less than $50

my trucks are always driven so if i've got the frame coated with red clay mud from haulin stuff i like to power wash it off the POR 15 at 10% the cost of powder holds up well to this type of longtermabuse reg paint will not hold up like that. i've had frames painted in POR15 after 5years of heavy real world everyday highway use with just a powerwash look like it was painted yesterday

Have you had any problem with the color fading or having a milky appearance?

I have read POR-15 is UV sensitive. I don't think the frame will get any direct sunlight (insert witty comment about rolling the truck here). Anyone know if indirect light will cause fading etc?

A local guy used POR-15 on his frame ('67 Ford). It looks awesome and finish appears very durable. He is very pleaseed with the results so far.

I used Rust Shield by Sem. bought at auto paint shop. Brushed it on and it is very smooth and seems to be very durable. Used the gloss black.
