Going on more than 3 months with tons of rain, snow, road salt and car washes and mine hasn't appreciably faded and definitely no flaking. But I used the tire gel, I don't think there was bed liner gel available when I did mine. The applicator that comes with the tire gel is great - it's 5 x 2 x 2.5 inches with a thick foam blue "handle" and a softer gray spongy part.

Your second picture looks really weird, almost like the gel had seperated in the bottle and that part got the thin part of the mix.
