Zymol Concours water behavior at 16 weeks.

Not a bad effort 16wks!! (link to wax?) can't help to notice in the vid it looks like your erm.....peeing!!! lol
 
I never got more than 2 months from Concours, so I'd suspect FG is helping it along a fair bit. Glasur seems to easily outlast it, but you don't get quite the sharp finish with Glasur, compared to Concours.
 
I suspect FG is helping, only FG'd it 3 times in 4 months though.

never had less than 6 months from a single layer. Even through the harsh winters. With only snowfoam, washing and various QDs. Only moved to FG in last 4 months.

Not even through half a pot in 28 months and done a friends car too.

BTW Field Glaze is fooking awesome!!!
