During the summer I used FK425 and OID instead of Pinnacle Crystal . It was better, but I only left it on for a couple of weeks before trying something else.
yakky, Souveran was the only product (ever) that drove me crazy. I kid you not I had to either do a wash or wipe down twice a day. After a few days I said forget it. I stripped it and used Zaino.
Even though Zaino was a PITA with the high humidity, it didn't attract the pollen and dust that Souveran did.
In my experience with both Souveran and Zaino they are real good products, but in my area I know when to and when not to apply them.
Out of all the carnauba's and sealants I have these are the only two that are like this.:nixweiss
