Megs Quik detailer. The red/maroon bottle. Doesn’t leave anything behind and can be used as clay lube. It’s the easiest Megs product I’ve used. It doesn’t streak in direct sun for me and wipes off really easily. I’ve used D156, it’s the ultimate quick wax version in a gallon, which can be used in the sun, but streaks if you over use on super hot black paint. Meg’s Final touch is another good one can be found at your auto store. Can be diluted 1:1. Optimum no rinse is another option.
