Installing metal Porsche lettering question.

[fallingat120mph]

Doing something different with the letters and installing on an X-Faktory grill. Just wondering if you keep the black adhesive "goo" on the push nuts or remove???

It seems like its on them for shipping?





Painting everything black and have a feeling the black adhesive will dry up and fall off over time.


Just curious,

You prompted me to check my badge emblem that I removed for a paint correction and didn’t find any gasket rubber (or goo substance) on the speed nut retainers that I intended to add and will.

Anyway, in my opinion, add the goo to the backside of the speed nuts enough to fill the hole too.
Car washing and dirt will allowed to penetrate without it, maybe even create paint damage in the hole if any contact is made from the letter positioning or waxing or wiping motions.

As far as I know this material is a water repelling non drying mastic to act as a water/air barrier. Seen this on car roof antenna penetrations for radios. Works better than a grommet for sealing out water in those instances and doesn’t degrade from UV etc.

For what it worth: I don’t exactly know what the compound is exactly called or named, not even my hvac contractor knew what it was called. It was used on my old house ac unit where the copper pipe goes into the unit. Keeps condensation from dripping back into unit electronics if pipe ever sweats.
Stayed sticky and soft, and tightly sealed both return air and moisture but after 20 yrs but he tossed it out with new replacement ac unit and used a different type that looks like gray plumbers putty but hasn’t turned hard yet after 3 yrs on my new ac.

As one can see, my speed nut doesn’t currently have a gasket (shadow present). That goo substance would seal this and add cushion to both the emblem and the keep water and dirt from damaging the sheet metal hole.

I would think that a little RTV on the outside of the hole, or around the peg to seal water out of the void would benefit long term.

Thanks gents! I will keep it on but trim a bit.
