Hi, different ways to do this but also a word of warning.
The rear three quarters are prone to stone chips, particularly the drivers side. The standard Porsche 'Sharks fin' are hopeless as they are not large enough. The bottom third of the 'fin' will get chips all around it.
Depending on how bad the chips are already, I would suggest you have a PPF layer that runs the length of the sill and then up the rear arch. This section of PPF plus front, front wings, mirrors and bonnet is typically known as a 'track pack' as it protects the most vulnerable parts of the bodywork.
See my old GTS here. Look at the door handle then follow that line to the rear wing. You can see a faint line. That is the upper limit of the PPF. You could of course have the whole wing done.
The Warning!! After having my PPF done I got a significant amount of gravel rash on the drivers side. It was VERY bad and I really thought it would need a respray. Before removing the PPF (which was XPEL), I spoke with a GOOD bodywork specialist who spent a lot of time on premium cars. He advised that for this area of bodywork, you cannot just spray and blend it. The rear wing is a single piece of bodywork that extends up over the windows. If you just mask the frames and spray, eventually the edge of the paint will peel because it cannot be sealed. Therefore the frames and glass have to come out. Part of that is riveted in so refitting needs doing properly or your also going to have problems with water leaks. When this happened to me it was about 2.5 years ago and was estimated at £1600+VAT (thats one side).
At this point we decided to remove the PPF and see how much damage there was.....I was relieved to discover there was NONE! Brilliant stuff!! It cost £200 to get the old removed and replacement PPF fitted.
So, my advice is that depending on how bad the chips really are, it may be enough to clean up the paintwork as best you can then apply PPF. If you want to make it as new then to do it properly is quite an involved job.
