HI all. I'm rebuilding the roof on my 97 TC800. Had all the usual issues. It's off and upside down. I'm sanding the glue and cleaning to prep reassemble. I'm rebuilding like factory did with marine ply, 1in Styrofoam, and 1/4 ply. What is best glue for ply frame? Best glue for Styrofoam and interior 1/4 ply. Would West epoxy and mat work to patch aluminium. Holes from corner brackets and a roof rack screwed into Styrofoam. No big ones.About 1inch from the brackets. Also the roof center seam has leaked. I will support and hammer, but what is the best way to seal It? Any suggestion on how to prevent sagging?
