Re: Detail between the letters?
First off you should be applying your wax so thin that on a light colored car you actually have a hard time telling where it's been applied and where it hasn't. If you apply wax to a black car and when the wax hazes over the car looks white, you've probably used enough wax to coat half a dozen vehicles. Remember that any haze you wipe off is basically product that you're throwing away - a car as small as the Crossfire can be fully waxed with less than 2 oz of product. Seriously.
Having said that, apply your wax to the areas between the letters and wipe it off with a microfiber once it's fully hazed. Work that microfiber as close to the edge of the letters as you can, even folding it over and using the edge of the towel to get as close as possible. You're bound to have some wax residue in the tightest areas around the letters, but also around the side marker lights and other tight areas. Spray a little quick detail spray onto the area and brush lightly with a soft bristly toothbrush or small paint brush. The QD spray will loosen the dried wax and make it very easy to remove. Wipe up any residual QD spray with a clean microfiber and you're done.
Yes, it's a fine detail, but that's why they call it detailing
