Anyone try Roof maxx or anything like it? extends roof life by 5 years/treatment

I just watched one of the videos on there and when he bends the shingle back prior to treatment he’s trying to break the shingle by completely folding it in half. Then he tries to say after the treatment it’s somehow flexible and gently bends the shingle. No where near the same test. The video seems misleading so the product probably is too. Look at 0:22 and 00:49

I agree with Harold. You could bend a brand new shingle back on itself 180 degrees and it’s going to break and especially if you press on it with your fingers. If the shingle looked even remotely more flexible he probably went back out when it was 15 degrees warmer. As Harold mentioned he didn’t come close to bending it back as far the second time. Shingles repel liquid so I don’t see how they can absorb anything to make them more flexible. Looks like snake oil to me.
