Sealing under slideouts
My Cardinal has 5 slides. I have just recently had to replace floor on one due to water getting in from under slide out. Slide out has a black mesh looking material under it. The water would travel down the side and travel under slide and the water entered through what looked like screw holes. I purchased a tape that is used on mobile homes called flex mend. I'm looking at 2 product.
One is proflex & the other is flex seal. Has anyone used either one that is brushable? If what results did you get? Thanks
