Been proven by whom? Abrasives are abrasives and particle size makes a difference. That's what the CD test will reveal. If you want to make a belt sander example, try belt sanding with 600 grit vs 60 grit. The 600 will strip the finish, the 60 grit will gouge right through the wood. That's what the CD test is revealing, the grit size of the polish which is nearly impossible for most lay people to assess. So if you think polish grit size doesn't matter then sand your table with 60 grit sandpaper, obviously grit size matters a lot.
The point I'm trying to make is NuFinish is harsh, extremely harsh. If you polish a CD or your paint with Nufinish and compare the finish left behind by a dedicated fine polish vs NuFinish you'll readily see in a bright point source light just how bad a finish NuFinish actually leaves.
Every person I've known who claims NuFinish leaves a good finish changes their mind as soon as I show them what their car looks like under point source lights like in a well lit parking lot at night. The swirls NuFinish leaves are horrendous.
Claiming NuFinish isn't bad for you paint is like claiming rubbing rocks into you paint is harmless because NuFinish's abrasives are among the coarsest I've seen in any polish.
Ask any detailer if they'd regularly use a rubbing compound on their cars. They'll tell you that's a bad idea. Sure it'll clean the paint, but it also unnecessarily abrades the paint because of its harshness. NuFinish's abrasives are even harsher than M105 and M105 is a very strong compound already. Why use a polish that's even more abrasive like NuFinish?
If you really think that I assume price equals better, that's wrong. Price the cost of Meguiars Ultimate Compound and Polish and Collinite. Very reasonable even compared to NuFinish. And those two will provide better and longer lasting protection than NuFinish all the while being gentler on your paint and leaving a much much better surface finish.
