I`m also unsure what `optimal environment` means.....but I really do not see how this product will last 12 months, or beyond, if not topped. I did give the car a good wash, and the hydrophobics did return, but to a small degree. I will give it credit, it does hold on to it`s gloss.
The environment I’m referring to would be one not faced with rain/snow, not daily driven and washed once per month. Still very slick, extremely hydrophobic & easy to clean.
I’ve also used it as a maintenance polish for coated vehicles, as a final polish and as a primer base for a coating.
