My grandfather sold shoes for more years than the ages of everyone in this post combined! I sure know how to polish a shoe - spit shine and all! I remember having to stand before him as a kid every time I got a new pair. Even in his old age, he would bend down and examine the fit and either give a thumbs up or thumbs down. Geez, I haven't thought about that in years!
Many times with my carnauba application I spritz my applicator with Eagle One Wet n Shine and do two light coats, allowing the first coat to just about haze up before I apply the second coat, one section at a time. On removal I spritz the EO on the surface and buff off with a MF. If I am using
Souveran, I use the PCM QD. This is my personal "spit shine" method.
