I think Meguiars makes the best products on the market. They beautify the pant, and do a good job protecting....and don't use the water bead test to see if your wax is holding up. Water beading on your paint is related to surface tension. Meguiars formulates some of their waxes so that the water does not bead. If it beads up and doesn't run off, the water will dry and leave water spots, chemically etching your paint.

I remember Consumer Reports rated the Meguiars rated the Gold Class wax low for this very reason, and Meguiar's is like "duh", we formulated it to not bead.

I use this stuff, and it's incredible:
