Have used the IP and FPII with great results EXCEPT the products "powder" and leave a chalky residue dust behind especially in door handle cracks, along the air vents, etc. I usually take a detail brush to clean out the dust/chalk left behind but never seem to get everything out. When it rains, whatever is left behind in the cracks leaves a white trail where the rain drips away.
Gotta belive this is a typical Merzerna issue. How do you deal with this? Suggestions? Advice? HELP!!
