well the leaf blower will get most of the water off, you still have to remove a few spots. For those you should blot up and down, avoid wiping sideways when drying.
as for water spots, Personally I never leave a freshly washed car "bare". I always follow up with a spray wax booster or an anti-static spray using the short nap (non-furry) side of a microfiber towel or a dedicated concourse grade
buffing towel. At the final buffing stage the paint is presumably clean so using the prickly side of the mf towel is overkill and if the towel isn't 100% clean it will cause swirling. Another reason why using different color towels is helpful. I only use certain towels for removing paste waxes, certain towels for sprays, cheaper towels for wheel/interior/leather cleaning and others for final paint buffing. The towels last longer for me this way.
