My '09 997.2 has 11K miles on it. They came unpainted and are now showing since of road rash (especially near the rear wheels) and overall has a dull look. I am not a big fan of painting the skirts to match the exterior color and like the contrast of the metal and plastic trim. I would love to have the look where they sparkle like new in a satin finish after every wash. What suggestions does the group have:

1) Nanocoat (like the GTS side skirts).
2) 303 Aerospace protectant.
3) Black wow.

I worry about the durability of the protectants in the setting of weekly washes. Ideally I would want a "permanent" solution but can live with coating a protectant every 3 months or so (would prefer not do do it more often). I am thinking nanocoat. Is it even possible ? Has anyone done it. What cost am I looking at ? Thanks in advance for your assistance/suggestions.

 

From my experience with using it on interior pieces, 303 will not give a long lasting 'shine' to the plastic. I would assume it would be even less so on skirts exposed to the elements.

Black Wow may be your best bet. Heard it does wonders on black trim pieces. I don't have any exposed plastic on my exterior any longer or I would try it myself.

No experience with the Nanocoat.

 

wet sand with 600 or scuff pads then paint with SEM Bumper Coater. this is like all the other black molded plastic parts like grills, door moldings , spoilers.
This will color them and seal the porous plactic so no more staining and white fading
