Now in regards to your Insert Trim molding. Last year at the Amana Rally i noticed a New W/J that the trim insert of 1 Slide was broken in Little 1" long pcs. The owner said he never noticed it! MR SUN has a lot to do with the lifespan of Plastic/Vinyl parts on RVs,where and how it is stored/parked ect. Add that the rolls of Insert Trim come in 1000' Rolls and there can be a BAD Roll from the Supplier also you can get results like you have! Ours is still Flexible but Not like NEW it is a 2010!
