I know this has been asked dozens of times and I've searched, but wanted some specific advice. I ONR wash and QD my daily drive about once a week if not more (Carbon Black BMW, the same is applicable to the GF's daily drive Jet Black BMW) . What do the experts advise as the best sealant for winter in the Midwest given the aforementioned wash/QD regiment? Options: FMJ Jetseal 109 FK 1000P Number of recommended applications is also welcome. Thanks in advance!
