Pinnacle black label paint sealant update

Well it’s just shy of the 2 month mark since I applied diamond paint sealant. The water beading has been great so far and shine retention as well. However just recently the beading was gone on the lower half of car but was great on higher parts good/roof/trunk. I just washed it today and went over it with a quick detail spray and it is looking as good as the day it was applied and just as slick. Seems the lack of beading on lower half was due to dirt accumulation as I did go awhile without washing it till today. After washing I hit it with a hose and it is sheading water again. I would have been rather disappointed if the beading stopped after just 2 months on the lower half especially on a product advertised to last up to a year. I’ll see how it is holding up in another couple months, but so far so good.
