It would be interesting to see the durability of this. Opti-Seal was one of the first LSPs I bought - always liked the application process, but durability and water behavior was always a bit lacking, even then, and more so in comparison to today's products. Hyper-Seal seems to have great hydrophobicity, and if it lasts for 4 to 6 months or more, I'd be fairly happy with that.

I got the same results as this guy. Not good.

Optimum is one of those brands that through the years has been overhyped.
