M205 will finish great but it needs to be worked in a different manner then traditional finishing polishes.
With M205 do not reduce pressure toward the end of your buffing cycle, instead maintain constant pressure and speed. Why?
It is the same reason that when you wet sand you want to keep constant pressure on the sanding block, to make sure that the abrasives are firmly and evenly 'engaged' on the paint to produce the most level cut possible. SMAT polishes work in a similar fashion.
On a recently 328 Ferrari that I worked on I was getting the faintest micro marring with M205 and a Lake Country Black Pad. I pulled the Ferrari into the sun to 'tune' my technique. I noticed to that the paint looked amazing as I was polishing it (under the polish film) but as soon as I lightened up the pressure I could see visible micro marring occur. However if I didn't lighten up the pressure no marring ever occurred.
These are unique polishes (M105/M205/M86) that do require us to adjust our technique to match their unique working proprieties.
In the past I have always been skeptical with having to change my style to fit the product, because I have gotten such great results from other products and processes: If it ain't broke, don't fix it....
BUT, M205 is worth learning, because I can do my final polish/jewel step in 1/4 the time (20-30 seconds), finish out to just as high of a gloss if I spent 2 minutes with a rotary, and 100% guaranteed that no holograms will ever show up...
Just my two cents, worth 1.3 cents with today's economy, but luckily worth three cents when inflation kicks in.
