In Part 4 of this series, Marcos and Rainer show great tips and tricks on how to installer the laminated window perf on the roof of this VW Golf R. The graphic has to align pixel to pixel so they show a very good flow on how to make sure it lines up perfectly. In addition, the molding on the sides is flat to the glass which, if a knife is used, the chance of damage and low quality is high. To neutralize this they use a combination of Perf Line and precut black gloss edge seal tape. The final result of this roof is super high quality and top durability all while leaving the antenna and spoiler on. This series is a masterclass so we hope you watched it and came away with the skills to lower your install times and increase profits!
