does anyone know of a solution to stop rock from being thrown on rocker??
What Porsche owners are doing in select high impact areas is putting a
second "sacrificial" layer down to avoid penetration......maybe a little late for you if you already have penetration and damage. I attached a picture of where some Porsche owners tend to apply the second "sacrificial" layer but that also will depend on how you drive and whether you track your car or where find the damage most significant.
...I've been told by some, I tend to be quite opinionated. Well, to that I make no apologies, but if we're honest, probably most of our forum members are too. I do not profess to know it all. With that said, (get ready for another opinionated response), just when I thought I heard it all regarding PPFs,....Really?.... a second "sacrificial" layer? I'll say again, I feel people are going PPF crazy and still feel many, who are unaware, are being lead to believe they're not doing due diligence if a PPF is not applied shortly after delivery. Yes, I get it, the overall rationale, (all previously discussed), especially heavily tracked cars, but I wager most PPF'd cars do not fall into this category. I still question potential paint issues after long term PPF's, say 10 years down the road or less, or do the manufacturers recommend replacing said PPFs at certain time intervals? If that were the case then I'd question ROI. I'm also not convinced all these "penetrations" would have caused definitive chips if a PPF had not been applied, after all there is a certain amount of "hardness" and yes chip resistance to a good paint process. The PPF is obviously softer..can't chip but can be "sacrificed", read punctured or torn. So will I be PPFing my 2019 GT4? Highly unlikely. I have been and will always be a fan of a good quality waxing, although I'm intrigued by the concept of ceramic coatings, assuming they actually reinforce the paint once applied and do not potentially create a more brittle surface. Once again, my non expert opinion...to each their own...so those in favor, PPF til your hearts are content! Hats off to those of us who are non conformists!?
