My friend and I last week did the MRT Louver install. Took about 3 hours including the pizza. Mostly measuring, measuring , measuring, then gluing on. Rinse and repeat. I let them sit for 36 hours in the garage before starting the car. I did not put on the prop rods yet as I think they will rattle. So far about 10 days of use everything is tight and stay that way. The key was the 3M adhesion promoter. Liquid sticky
Comments from the last week car meet is a lady said now my side 1/4 windows louvers need to be the semi-matte black, your thoughts on that?
