Does anyone have experience with 3M 4000 UV adhesive/sealer? It was mentioned on my recent visit to Newell as what they're using to seal the outer slide seams. All my usual sources are out of stock, so I haven't been able to experiment with it. But is sounds ideal - dries to a slightly flexible but strong hardness (I've had cracks in my 5200 repairs which seems counterproductive.) Both 5200 and 4000 are designed to be applied to boat hulls in the water. They need water or at least humidity to cure. So I have high hopes for the 4000 UV.

BTW, for window caulking, where the factory sealant has oozed out from between the frame and exterior skin, I like Sikaflex 221.
