This is the saddest part about CMW, its basically a low beading lsp.
Beads are not everything, if they dont sheet off you get water marks, but yeah. Its not the best beading product, which is why some people suggest its a low durability product, which is wrong.
Two things you can do:
As part of drying shoot some QD on the surface of the car, it will help reduce marring from the drying towel, disperse water and add shine all in one go. Quickshine from Clearkote should also add some beading!
Purchase something like Stoner Bead Max and spray that on the car after you washed, that should add some beading!
