Have 2 cars to polish in next 2-4 days, HD speed, Rupes UHS or yellow/Keramik

Never had this issue with HD Speed. In order to make it work for me, I'll do 4 passes at correction speed and then 2 passes at low speed.

Me either, and I remember David Fermani confirming on this forum some time ago when he was representing 3d / HD that their were no "fillers or oils" in HD Speed.
