There are roofs and then there are Ferrari Portofino M roofs. This roof has 3 levels when opened up and very tight rubber molding on all the edges. For a color change this would be a challenge but to do with a one piece full print piece makes it extra hard. To solve this and ensure a high quality result, Rainer turns to smart prep with fine line tape, 3M Perf Line and 3M Design Line to set up the cuts for after the main install. For finishing, be sure to see the methodic protocol from Rainer and Martin as they finish each edge with no tension. This is a great watch for all levels, especially advanced installers.
