Menzerna polishes do not fill, period! The only filling products from
Menzerna are the glaze APO60 and the wax PO73. All other polishes are for use in bodyshop environments, so they do not contain silicone or clay fillers. What some see is the improper break-down of the polish, and/or any residual waxes which can lead to a filling type of senerio.
If you experience "filling" then A) you're not breaking down the polish fully or B) there is residual wax or other product left on the finish.
Menzerna polishes for Ceramiclears were really designed for spot repairs/correction while on the assembly line/off line and these manufactures were specificly trained by Menzerna and PPG on what type of tool, pad, rotation speed, pressure, duration etc to correct a finish.
Outside of this, using Menzerna does have a learning curve to use correctly. But once one can grasp the proper use of it (tool,pad, pressure, duration etc) then you'll have the best finishing capabilities.
I came from a very heavy 3M shop, to Menzerna after one of the owners got samples prior to Ceramiclears, and we were learing this product. Once learned, it was outstanding, and we ditched the 3M. Once the Ceramiclears started to arrive, we had Menzerna ship the product for us to test on "test fenders/hoods" that we shot with the new finish as per Mercedes spec. It took some time to master, but again, we were all blown away with the result.
In the end, it was all Menzerna exclusivly including the glaze.
For non professional use, it can act in strange ways if not used with the correct pads/tools. If some remember the issues with
Final Polish years ago which lead to FPII for "consumer type" use and other formulations from Menzerna for hobby use. Such as the Blackfire SRF polish which is licensed from Menzerna. More geared to hobby use and not so much pro use.
In any event, there are other polishes out there and so far none has impressed me as much as Menzerna has. German engineering does have an advantage in abrasive technology!
Maybe one day Menzerna will offer "Webinars" and other trade specific training for both pro and hobby use. Until this happens, it's still trial and error on learning the product just like any other product.
