POR 15
« on: April 14, 2011, 05:20:01 PM »

Today I used POR15 for the first time ever on some suspension parts I'm restoring and I learned something....

It's SILVER!!

Why have I always thought it was black?

So.....I obviously can't have a 2-tone suspension (or CAN I???).    Do I paint over the POR15 with black paint?  Is that how this works?  What have you guys done?

It comes in 2 colors
 
The bad news is, you need to use the POR primer for paint to stick to it.
 
I don't use that stuff.  I use the Eastwood rust converter and paint it

scuff it up with red scotchbrite and paint over it with semi gloss black Rustoleum.....the silver POR15 will protect the metal and the Rustoleum is cheap and looks/lasts well....my friend is painting his complete chassis with it

I looked at the can again today.  Just above the barcode (on the back) is the text "silver" in a plain-jane, normal-sized font.  That's it - and there's nothing on the front.  If you didn't know to look for it there, you'd never see it.

It's certainly overpriced.  Well, I'm in the middle of this mess, so no way to stop now.  What brands do you use for this sort of work?

Por15 for sure works extemely well, great protection and long lasting.

The Por15 I used a while ago was black btw.

I'll tell you what does a great job, thank you Bob.  Soaking your parts in a Lye solution.  Old grease, paint, everything except rust comes off.  But it does attack the scaley rust on pieces though.  Then a chaser of the rust converter.  I usually scuff the parts with a pad before I prime

its possible i'm mistaken steve when i had my fury someone told me about por i thought it was you but it was prob someone else. I used it on the fury and it worked but i hadnt gotten to the stage of painting it before i had my electrical disaster under the hood.

POR 15 doesn't take UV light well....it chalks up. Therefore it needs to be topcoated if it's going to see any sun. Silver POR15 is sold on the premise it has metal flakes in it and builds up weak metal better (like pitted gas tanks or trunk floors). We used the black to pour into door bottoms for the ultimate protection from rust.

I used the black POR to paint and seal up my Auto Temp 2 servo unit on my Imperial after I epoxied and rebuilt the cracked plastic body. I painted the water passages inside also.

POR needs moisture to cure....if anyone had a problem with it sticking it probably was applied when the humidity was too low.

The lye bath works well, but for rust I like Dupont 5717 phosphate coating for tough parts, Ultra One for the delicate stuff. I used to fill a spackling pail with one gallon of 5717 and 4 gallons of hot water. Even when cool it works wonders. Plating parts always turned out better when I soaked the parts overnight first before sending them out. Paint sticks great, and the surface is etched just enough.....all pits come clean.

On my Nova I did like Bob said, scuffed it and I sprayed on satin black
enamel over top the POR. Almost 3 yrs later it still looks
perfect.  The POR-15 Silver has extra metallic particles in it and
they recommend it for helping fill in rough metal, use the Black for
smoother metal. I used the Silver on scaly underbody areas and it
worked well.  Not cheap but if you do it right it is almost
impregnable.
