Thanks, good to know. I may need to pick up some M105 or something. Guess my test spots will let me know. I'm hoping for the M205 on the tangerine hydro-tech to do the trick, then was thinking about just finishing it off with the DP polish prep on the tangerine as well. I'm not sure if the crimson finishing hydro-tech pad is comparable to a standard white pad. From my research people generally do 2 step with orange then follow up with white. I got sold on the hydro-techs watching Mike Phillips promote them with the thin is in philosophy. So sticking with hydro-techs I'm looking at tangerine and crimson. Get's a bit confusing.
