Hi, I am readying my sunroof slide panel frame for the headliner shop next week for covering and headliner installation. I have read many conflicting posts here regarding this. I believe when I removed mine two years ago, it had 1/4 inch foam along the bottom rear section, and felt along the bottom sides. Some pictures show some rolled up cloth under the middle section between the frame and headliner material. I plan on using felt tape I found, (not very thick at all, so maybe I will double it). I am interested in your input on the matter before I complete the job. What is the felt's function, cloth between frame and material, etc? Many thanks,
Scott
