I use Black Magic Wet Shine on my CT because CReports recommended and I usually trust them with test such as wax because I can’t test them over time like they do. Comes in a red 16oz bottle and it’s a liquid. Goes on really smooth but can be a little more trouble taking off than others I have used but if it’s been through time test…its good enough for me. Wax has held up good for 4 months now with good beading in rains. I use this to mostly protect from bird poop, sap, and highway bugs. Yes, I know I will hear people say I waxed too soon but facts are that paint is made different now days and dries quickly after painting not counting time on dealer parking lot in sun.
