Thought I'd give CarChem Lockdown sealant a try. Lack of use and correct wash technique meant there's been very little maring or contamination build up requiring claying or tar remover.
Washed and dried, this was then applied in cross hatch motion a couple panels at a time given the low single digit temperatures. It's currently sitting on top of my go to drying aid Turtle Wax hybrid sealant, albeit a few weeks old. These will either compliment each other or il be left with little to no protection in a months time.
Very nice to use, easy on easy off however can imagine in the Summer months would dry on the surface rather quickly. Left it on the rear glass a tad longer than idea and the rainbow flashing proved a little firm to buff off.
