I went through this. I glued my old trim on with weatherstrip adhesive when the clips started failing. Later I cracked my windshield and upon replacement, I had to ruin my trim to get it off. The glue was just too strong. So... If you have to buy new trim which I did, each piece is $75 from BMA, I don't think I would want to glue it on. I would suggest looking for a used piece and gluing it on. the weatherstrip adhesive is available from autozone or whatever parts store you use. Then if you need to replace your windshield, plan on buying new trim and clips. The trim is just cosmetic, it has nothing to do with the seal or the windshield.
