As a kind of experiment, I've just polished the hood of my sapphire black BMW using a PC
Prep :
SSR 1 - Polishing Pad
EZ Glaze - polishing pad
followed by 1 side PB EX-P, the other CG M-Seal - finishing pad
then further subdividing each side to Natty's Blue and P21S - hand applied
Result....
I can see absoultely no discernible difference in terms of Depth, pop or gloss between any of the areas
Should I expect to see differences in durability?
what have others found... I was expecting at least to be able to see some difference to the finish.
