Custom Center Caps for Porsche Wheel [from CAD, prototyping to finish]

[Nine8Six]

yea those are the standard Porsche lugs. You can't paint those but can clean them real good from time to time with a rotary steel wheel, or a hand SS brush, if you almost love screws too! They come back to life with little effort.

I covered mine with little black plastic hex caps I got for $1. I cover the inner wall surfaces of those caps with grease using my finger, leaving about 0.5 thick of grease in there. Those sit quite tight onto the hex head and lugs behind stays nicely protected and clean.
