also, wax goes on a lot smoother and easier after you claybar (waxing becomes less of a chore and more of a “i should do this more often!” experience).

i plan to do this at least every other year now. of course, keeping a good coat of wax on your car (that is, waxing several times a year) should deter a lot of the contaminants from sticking in the first place.

this is extra important if you park near railroad tracks or industrial areas where particulate pollutants can be especially aggressive!

What I use: works great, smells even better.
