Brown Goop on Trim Sheet Metal Screws--Tail Panel--69 Charger

[Chatt69chgr]

The #8x1/2 inch washer head sheet metal screws that hold down the stainless steel trim piece extending across the rear tail panel of my 69 Charger from one tail light to the other have traces of a brown goop on the threads.  It appears to be used for sealing the thread to body interface to prevent water from getting into the trunk.  Does anyone know what this brown goop is and where you can get it.  Or do you just have to buy the screws new with this already applied.  I wanted to use stainless steel screws to replace the originals.  Of course, none that I can find locally have the brown goop on them.  I suppose I could use a dab of something like permatex or silicone seal to achieve the same purpose.

Back in the days they did'nt had acces to sealers like nowadays. They used stuff that was oil derivate based.

I'd say use some body sealant wich you can buy in a can or tube. Dip the screws in it as you go. Better than silicone sealants as the body panel sealants stay kinda flexible.

Thanks for the info and suggestion on the use of body sealants to seal sheet metal trim screws.  In fact, I just got three tubes of this to finish up some places that my body man missed so I'vew got plenty.  Don't know why I didn't think of this.  Again---thanks six-tee-nine.

You can buy the screws for the wheel well trim with that goop already applied. I'd think you could get the trim screws the same way (might even be the same screws). I think it's cosmoline or some such thing. Since they were running the screw straight into the metal it would leave it bare (no primer) so this was a way to get some sort of protection against water/rust. Based on the number of rusted out screws/holes in my cars I'd say it obviously it wasn't a great solution.
