Actually it is not false, well not sure about what you posted. I use 22ple on my customers cars which lasts 2 year. I use it on my personal car as well. Opti-coat as far as we can tell lasts forever. I've talked to people that have had it on their car for 5+ years easily. The only downside with opti coat is IMO doesn't produce the same shine and depth as 22ple does.
