After a finishing polish (106 or Ultrafina) what would the prep be for applying FMJ and can it be used over glazes aside from Menz 115 ?
After removing the residue from polishing with a MF, I would just apply FMJ straight over top. I would however, top FMJ with Collinite b/c the FMJ doesn't seem to last. Here are some examples of what I mean: fornicating mosquitos - Auto Geek Car Care, Car Wax and Auto Detailing Forum Black 350Z with Menz/FMJ/Collinite - Auto Geek Car Care, Car Wax and Auto Detailing Forum '04 Saab..1st engine detail & lots of pics - Auto Geek Car Care, Car Wax and Auto Detailing Forum
To prep for FMJ, I typically use either a 50/50 IPA/distilled, or the Menzerna Top Inspection. I've understood that the paint needs to be free of the polishing residue to adhear properly.
