When you guys are applying your wax, do you go right to the edges, or leave a border so you don't get wax into the "cracks"? Also, what about stuff like the Mazda hood logo and tail nameplates? Do you wax those like you would the rims?

If your using Zaino -- then go right to the cracks and cover the emblems etc. One of the best things about Zaino is that it leaves NO WHITE crap in the cracks and crevices :D

p.s. - I also Zainoed my rims -- looks great and the dirt/brake dust comes off much more easily.
