Very true. Expect to get anywhere from 3 to 7 years out of the Opticoat depending on conditions etc. Being that I drive the Genesis about 5,000-6,000 miles per year and no winter, I'd expect it to last the rest of my ownership anyhow
Most waxes last about 1 month for the average driver and 2 months for a sealant, so if you're planning on always having paint protection on your car, you should be waxing your ride probably every 6 weeks.

I waxed my Genesis 5 times in the 1st year I owned it with the Liquid Ice. Each year I spent less and less time detailing the car after that
