So, it's 1/2 way through winter, how does your MINI look.
Both of ours look great. The 5 coats of Zanio in late October
are holding up great so far. 2 big ice storms, snow and rain, plus lots of road salt have all washed off with many trips to the wand wash.
It's raining here now, just out walking the dog, and both MINIs are beading up, and shining under the street light

.
I'll post some pics tomorrow, as long as they are not buried under snow.
Bottom line, protect your paint with a good sealant, and a little elbow grease
