Okay. couldn't wait any longer. I replaced with standard 1/2 inch "D" stripping. Also found that the tape on the slide out wasn't installed properly and have creases witch can allow water to seep into the slide out. I'm using Kool Seal Elastomeric Roof Coating, to seal these seams. Worked for me in the past on other Rv's. @ coats on each seam. Anyway, I'll be ready to travel in a week.
