Not the Joe Gibbs racing engine oils, it's a different Gibbs and it's a penetrating/ conditioning oil than can be painted over.

Welcome to GIBBS Brand Lubricant

My question is this:

Has anyone used this product and then welded over it at a later time?

I want to use it on bare metal on my build, but will need to come back and weld over it at times. I would definitely hit the places to be welded with acetone or something similar prior to the welding.

I just don't want to use it only to find out all I get from welding is swiss cheese and porosity. That's not going to cut it on a cage.

Would love to hear any and all real world experiences with this product and welding.

Well, I figured I should follow this up with the fact that I contacted Gibbs and they said their product can be welded over and even painted over. It contains no oils.

So I have a case on the way. I'm going to put it on the bare metal I have already installed on the Jeep and even the new metal I have waiting to be used.

Tracking says it should be at the house on Monday. I got the idea from mcutler1 on Pirate. He's running a bare metal cage on his build and swears by the stuff. I had never heard of it before.

Got to play with it today.

Did a test on a piece of 18ga cold roll. Coated one side and tossed it outside. I'll keep checking it to see what happens.

Did a little weld test too. Sprayed it on some scrap and DIDN'T wipe it off. Then welded right over it. It didn't effect the weld at all, nothing. No difference.




I always wipe down everything I weld with acetone anyway, but it's nice to know if I miss a bit of the Gibbs in some nook or cranny, nothing is going to happen.

So I went ahead and wiped down the new front frame rails. Followed the directions, squirt some on a rag, wipe metal, wipe down with clean rag.
I did notice that it didn't do anything to the paint pen marks on the frame, but it did remove marks from a Sharpie. It's just something that I noticed.

This is after I applied the Gibbs.



I also tried painting on it. Wiped it on a spot on 16ga hot roll, right over the mill scale, then gave it a little rub with a clean rag, followed directly by hitting the spot with rattle can rustoleum primer.
Acted like it went directly to the metal. I'll get a pic tomorrow when I dig around on the spot with a screwdriver.

So, first impression is that this stuff is awesome. We'll have to wait and see what the cold roll outside in the back yard says in a few weeks.

Checked the piece of cold roll I put Gibbs on one side and tossed in the yard.

Gibbs side



Non Gibbs side



Didn't take but a couple days for the rust to start on the non-Gibbs side. Treated side looked pristine.

And here is the hot roll I tested painting over the Gibbs on. The time between applying the Gibbs and painting was only long enough to make a few marks with a sharpie and a paint pen. Sharpie and paint pen went on just like normal, as did the spray paint. You can see how the sharpie bled through the spray paint just like it normally would.



Spray paint dried as if nothing was between it and the metal. Even digging a screwdriver around in it didn't peal it up.



I have to say, this stuff is pretty amazing. Lots of things stop rust from forming, but you ain't painting over it, or welding over it.
