FMJ definitely degrades after the first wash. Beading decreases noticeable, but slickness is what really takes a big hit. HGAS helps to restore it, but unfortunately, it streaks on black for me. I suspect most oily sealants have similar characteristics. like UPP and Wolfgang. If I don't wash my car for a while, FMJ seems to stand up reasonable well. The slickness prevents dirt from adhering, so dust washes off easily.
It's also helpful to remember the distinction between the German Menzerna products (polishes, or most of them anyway), and the USA line, as the quality may not always be the same.
