wannafbody- Yeah, gas prices made a few of my trips pricier than I'd like this year too.
I dunno how much we can extrapolate about "carnaubas" in general based on experiences with 845. That Insulator Wax is some weird stuff and I get wildly differing results with it on different vehicles (and even on different parts of the *same* vehicle).
I don't have much experience with sealants, only having used KSG, UPP, and BF (and some playing around with FK1000P), but I just never have any issues with the carnaubas I use on our drivers.
Collinite's 476S, Meg's #16, and the old pre-VOC 3M Showcar Paste simply never leave me disappointed and always hold their own in comparison with the sealants :nixweiss I think there's a whole lotta YMMV stuff here, but if the waxes let me down I'd be the first guy to try something else. I keep going with the 476S and the #16 simply because they always leave me satisfied.
On your stripes, maybe they *were* just really delicate :think:
And maybe the time frame was just too long under the conditions. A few months is pretty long for LSPs IME, and only the 476S and layered KSG last that long for me without some kind of degradation. Even my beloved #16 needs refreshed or something after three months, but then so does the UPP/BF. Gotta say that I love the KSG on the MPV though, that's one LSP/paint combo that I like and yeah, six layers lasts forever!
Heh heh, I can hear what you're thinking, but I'm not ready to try Zaino as I just don't like it on my particular paints (yeah, I know, others do but I'm, well.. me). Maybe the FK1000P will blow me away and change me to a more sealant-oriented approach, we'll see. Til then I'll just keep redoing the #16 on my wife's car, yeah, wish it did last a while longer.
