I used the midsummers night more than any thus far. I upgraded to Katzkin Leather seats, and still use the ole Chemical Guys Leather scent, but can only spray under floor mats versus douching my interior like I used to. I also started using the Yankee Candle Leather, but nothing seems to really last. So I'm more on the kick right now of just buying Wal-Mart Black Ice fresheners, due to availability and scent isn't too bad. So, I'm mixing the Yankee Candle Leather and the Black Ice as of now until they run out. Then back to the drawing boards.
