I can't imagine keeping a painted lip spoiler. I know gents that have two to swap in and out of the body shop while the other is on the car. Does it look better painted? Yes. Does it look better to the point of making this practical? No (IMHO). I'm soooo much happier with my non-painted, black spoiler on my factory aero 997.

 

And I should also mention that mine is a garage queen seeing less than 1000 miles a year. I still couldn't handle a painted application

 

Just got mine put on. Decided to paint it to make it look oem

 

Mine is very flexible and is OEM, and came already primed from Porsche. They add a flex agent to the paint so that it won't crack. They can paint to stick to just about anything if they know what they are doing.

 

paint it and then get it clearbraed

 

Thanks to everyone on this thread. I bought it and installed it, it was so easy. Since I have black, I considered going unpainted. In the end, I followed GT3Tek's simple instructions to strip the wax, and spray-can painted it myself. The spray can paint is really soft, so it 'chips' easily, still for me, it was okay for now. I put about 4 layers of black paint and about 5 layers of enamel, and it looks okay. More patience and effort in wet sanding, polishing, etc. would yield better results. It's hard to tell any flaws now except if one's looking for it. So an option between real paint and leaving it as it is - just passing it on. $20 in materials and about 3-4 hours of effort.
In the long run, as it chips, I may need to redo what I did every so often, or get a real paint job on it.
I'll post some pics soon.

 

Now post some pics!

I left mine unpainted.
