I applied Alpha 1021 to a skylight and solar panels, but it appears ugly collecting dirt and looks to be failing exposing cracks, it is also super gummy like bubble gum? Maybe I’m supposed to be using 5121? The factory stuff after 5 yrs, still looks clean/white and firm, much better than the 1021 I put on. Anybody have an opinion if I should be using the 5121. Can anyone confirm the 5121 doesn’t collect dirt like 1021. Here’s a pic of the stuff I put next to the factory clean stuff.
