M205 really finishes best with the 7" black finishing pad from
Meguiar's. It was designed around that pad and it shows. Also, your pad for
M105 depends a lot on what you are working on. I have good results getting correction with the
Meg's 6.5" yellow pad on some of the soft/medium clears. On harder clears GM, Audi, etc., you will want a smaller pad for serious correction. Something like a 5.5" Orange should work nicely.
