por-15..... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

70-Chevy · 10-23-2005, 11:12 AM

Ive read some posts on this stuff and it seems pretty good. Im getting ready to rebuild the complete front end of the my truck. Now when I take off the control arms and crossmember and such, then grind and take off the old muck thats on there, can this POR-15 be applied to the parts under there and last awhile? Can I apply it just by brush? Im interested in this stuff and I need to know where I can purchase it from. Thanks alot guys.

cdowns · 10-23-2005, 12:01 PM

clean degrease and paint with a paint brush(disposable is best) a quart goes a long way www.por15.com

Boydness · 10-23-2005, 12:45 PM

I use and recommend it all the time.
Although, you do need to follow the directions for best results.
The parts need to be cleaned of ALL grease (they recommend Marine Cleaner and it seems to be the best cleaner to use) and then rinsed and dried. Metal Ready works great to anchor the stuff to the metal (rinse after applying and then let dry).
I use use cheap foam brushes (like 4-6 in a pack from the $1 store).
Now, you get the smaller ones, because you will want to pour large cans of the POR-15 into smaller baby food type jars (with a layer of plastic wrap between the jar lid and top, if you ever want to open it again). Then you can use a jar worth at a time without your entire can hardening up.
If you have anything left in the can, that needs to be saved, place plastic wrap between the can and the lid, and store upside down (with newspaper between the can's lid and the surface/ ground, in the event that it leaks).

Be sure to remember to stir not shake the products.
And becareful not to get it on you, because you will be wearing it for days, no matter how hard you scrap.

I can take a pick of the underside of my project jeep, if you want to see what 5+ year old applied POR-15 looks like...

How much do you think I will need to do the complete front suspension ans steering components?

cdowns · 10-23-2005, 03:07 PM

this stuff goes a LONG way for a front end and components i'd figure about a cup or so// do like he said about pouring some out of the can to work with//i drill 2 small holes in the lid and seal with sheetmetal screws// if the stuff is freash you can remove from your skin with lacquer thinner but if it dris well you wear it for a week or so till it wears off

silvertonguedevil · 10-23-2005, 03:23 PM

Does anyone recommend spraying the stuff....or just brushing it on?

Longhorn Man · 10-23-2005, 03:26 PM

Entinre under carrige..maybe 2 quarts.
As for closing the can and not getting it opened, if you wipe the POR our of the channel on the top of the can, then it'll come off again.

Boydness · 10-23-2005, 03:39 PM

Personally never sprayed the stuff, I have always applied it with foam brushes.

I had a gallon can once harden on me. The top most @ 1/4" of the POR-15 harden. I had to crack it open with a hammer and a chisel to puncture a hole to get at the liquid below. It was a pretty hard layer.
I like to think that the plastic wrap helps keep the air out of the can as well.

I like the baby food jars, if the lid gets stuck, then I just cut the metal lid open.

The metal screws in the top of the can is a great idea.

AKChevyman · 10-23-2005, 03:57 PM

Here is what I did I love the stuff First get a 1 quart canning jar with the lid take the Quart can and fill up the Jar then tighten the lid down very tight. I have had My quart like this for 3 months and it hasn't hardened yet. When you are ready to use pour some into a Plastic dixi cup and bursh from there make sure when you replace the lid on the jar to wipe all residue from the outside of the jar. I used my quart to paint my whole frame and steering parts and I still have a little of it left in the jar. Read the FAQ's on the POR 15 website they have all the direction on how to make this stuff work.

70c10swb · 10-23-2005, 05:54 PM

can i use a cheap walmart gun (i think its < $20) to spary a couple of coats if it ruins the gun?

cdowns · 10-23-2005, 06:07 PM

i've never sprayed it// if spraying i'd use EXTREME care//i'd think it wouldn't be woth the risk of the overspray and too easy to inhale and DIE there's a sticky in the paint and body section you might want to read B-4 spraying entitled "WHAY HAPPENED"//beside that there's the fact this stuff is so economical(very little covers very much) don't see you getting that with a gun the idea is not to build it up like paint//just get some and try the brush first you'll see

What was POR-15 originally invented for? Military usage?

Sometimes I see mainstream everyday store bought items orginally designed by the gov't in days gone by for issues discovered long ago!

When the stuff cooks it is not too "friendly", so I doubt it. It is not approved for Navy shipboard use, I know that for a fact...

Longhorn Man · 10-23-2005, 08:43 PM

it was designed for the restoration market.

I wouldn't recoment spraying it either, onless trying to get between panels, like in teh roof of the cab or something. If you are carefull, the brush marks are minimal.

we use this stuff all day at work, really is awsome stuff.

*chevytruckfan* · 10-23-2005, 10:05 PM

If you spray it make sure you use a resparator or you will end up in the hospital. It is a good idea to use one even if you brush it on.

Solver · 10-23-2005, 10:17 PM

I have both brushed and sprayed the stuff.
Figured I would get a smoother finish if I sprayed it. NOT!!
This stuff self levels well and by brushing you can get it on a little thicker.
air gun with the overspray it is -VERY- dangerous in the air.
The fine particles breathed in around respirator will harden in your lungs-- Yuck - don't do it!!
Just brush it on and be happy cause it will gloss nicely
Just don't expect it to stay glossy if any where is exposed to the sunlight. This stuff is not UV friendly. Will turn flat black in a couple of days if left exposed
Thats all I have to say about that

mplex2000 · 10-25-2005, 04:10 PM

I sprayed mine, every brush job using POR I've seen looked like crap. I did buy their solvent to thin it, but it seemed harder to work with (if I remember they said only to use 5% solvent anyway). Using an HVLP I just ran a little higher pressure than usual and it sprayed great.

POR says to use an organic respirator when spraying in a well ventilated area. That's what I did and I'm still alive.

redhead69 · 10-25-2005, 06:58 PM

I've brushed it on a core support with a respirator on, fans going, doors open--well ventilated area- and it about knocked me out for the evening. I felt light headed and very spacy after using it.. read the sticky about it (dont wait till after your done to read it like me).. and to be honest- I dont like the way it looks.

HOTRODDAD · 10-25-2005, 07:38 PM

I Have Found That Spray On Or Brush On Bed Liner Does A Good Job Too

redhead69 · 10-25-2005, 09:42 PM

Hmmm.. 15+ years of automotive and construction work and you think I'd know if I was sensitive to solvents... hey maybe somebody slipped me some drugs...

Painting over rust never seemed like a good idea to me anyway, and if your just using it as a protective device then why take the risk with all this talk.. Here and I thought I only argued on the bimmer forums.

*wolfthing2000* · 10-25-2005, 10:16 PM

Hmmm....

I have only brushed on POR15 and I always use a respirator if only so I don't have to smell the product. Never had a problem. If you weren't so experienced with using automotive paint products, I'd have suggested you check the respirator filters for saturation or deterioration. I'd have also suggested to check the mask for proper fit and sealing.

Can't say I know what happened, but you obviously experienced contact with the stagnant product's fumes.

Longhorn Man · 10-26-2005, 05:29 AM

I have to agree, your resporator is probably in need of attention. AS for the looks of the product.... it looks like paint...since you have to paint over it.

*wolfthing2000* · 10-26-2005, 09:00 AM

Zero Rust!!!

xam · 10-26-2005, 09:13 AM

POR sprays fine be sure to wear a spray sock (covers your head ). Por is basically a moisture curing direct to metal epoxy thats why it works great on rust it draws the moisture from the rust to cure.
