Had mine on for 2 1/2 years, started wearing off, some peeling, a little gray in areas.
I didn't want to use wax remover, not sure how the siding and lower paint would survive.
I took a chance, used barkeepers friend and re-cleaned the surface.
I reapplied using ZEP over the peeling areas after cleaning. Not a problem, came out just like the first time. Now, think I will start reapplication every year or so with one coat to maintain and keep it looking new.
It goes on easy. Using a white microfiber cloth works best for a very smooth application.
