A client brought us their $200K classic 1975 Porsche 911 930. The first question most shops would ask is "full-body PPF or partial?" We asked a different question: why use PPF at all? Here's the thing. Traditional paint protection film leaves visible seams along every curved panel. On a six-figure classic build with irreplaceable paint and iconic body lines, that's not a tradeoff we were willing to make. PPF edges lift over time. They trap moisture. They yellow with UV exposure. And on a car like this, you'd see every single seam line running across those curves. We've seen it firsthand. A white 911 GT3 came through with dirt-stained PPF seams visible along every edge. On white paint, those seam lines collect grime and stand out even worse. That's exactly what we wanted to avoid on this classic build. The 993 fenders, roof, and body lines make PPF a particularly bad fit. The compound curves create more opportunities for edge lifting and visible seam lines. And on a car with fresh paint that can never be perfectly matched if damaged, the risk of edge lifting and moisture trapping isn't worth it when there's a permanent alternative. So we applied three layers of Icon Rocklear instead. Our permanent coating system bonds directly to the paint surface. Zero seams. Zero peeling risk. 15+ years of protection against UV damage, rock chips, and scratches. The result is a seamless, invisible shield that preserves this Porsche's body lines exactly as they were meant to be seen. Another advantage: no disassembly required. Unlike PPF, which often requires removing doors, mirrors, and handles on vintage cars, Rocklear is applied directly without taking anything apart. On a classic vehicle like this, that's critical. You don't want to risk damaging irreplaceable trim and hardware. After the coating cured, we planned an aftercare process including wet sanding and denim pad finishing to achieve a true showroom-level result. That level of attention is what six-figure builds deserve. After eight years of testing everything (ceramic, teflon, graphene, PPF), Icon Rocklear is what we put on our own cars. Not because it's easy to apply, but because it actually works. For classic cars, it wins every time. No question.
