so what's the problem with the car wash? It's very high tech, brushless, and I've taken porsche cabs thru it for years.

They come out looking like this:

 

What would Ferdinand Porsche want? IMO, Put the crest on. It's better that way. It's just enough with it on and missing something with it off. We're so lucky to have these cars, might as well let them shine with a little gold "jewelry."

 

My vote goes to the black chrome one for sure. The colors look like theyre gonna match the carbon fiber perfectly.

 

I think that I found a solution. Porsche hood emblem sticker in gold and silver in 3D.

I have to agree I would stay away from car wash on the norm. I do think your car looks awesome. If this is the long term effect then stay with what is working for you. Looks great
