I take any durability claims by manufacture as a grain of salt..there are many factors to consider when product is used in real world scenario so durability claims i don't buy into them..Polish Angels products are good but for me they look initially but doesnt last long..
Exactly. You'll never know for sure how durability will really turn out until you actually try it in your climate and your situation. Some things can be estimated by finding others experiences in similar conditions and usage but that's still just an educated guess.
We have 3 cars with considerably different usage patterns; all protected with same set of products.
Car 1 will likely get to 3 years (if not longer) before needing to be completely redone.
Car 2 will likely never need to be redone.
Car 3 will get to 2 years at the most before needing to be redone.
Car 1 is about 5500 miles a year, no freeway, sits outside from April thru November but only really driven daily November thru April, short trips, no freeway.
Car 2 is daily driver in nice weather, April thru November, usually no-rain days only, always garaged, 5500 miles a year, rarely freeway.
Car 3 is year round daily driver, generally always garaged, 20k miles a year, 95% freeway.
All are in NE Ohio.
Same protection, varying usage far different likely outcomes. Freeway use, especially during winter, is very, very hard on a vehicles finish.
Having seen a lot of faded cars last time I was in Arizona, I'm guessing they have a whole different kind of nightmare to deal with, entire different set of circumstances to cope with.
Florida apparently has acid-filled Love Bugs that can etch paint if left for too long...another nightmare entirely.
Point being, no claims listed on a box can even begin to adequately predict longevity.
It's the ultimate YMMV scenario.
