If you can feel the scratches with your fingernail then they are too deep to get out. Wetsanding and using Meguiars M105 and M205 with your griots would make it look a whole lot better though. Even just M105 with a yellow or orange pad and M205 with a white should make it acceptable until you...
I've used APC and APC+ in my wash bucket, sprayed directly on the paint and in a foam cannon and have never had a problem. Pretreating bugs with APC+ works great as well. Just don't let it dry.
Why would you ditch the megs backing plate when you need it for the mf system? I would just get another backing plate for your foam pads. Fyi I've never had any problems with Lake country pads on a megs back plate but I haven't used the hydrotechs so maybe they don't play well with the megs...

I just used sonax and iron-x on some BMW wheels with insane brake dust specks yesterday. I spent about an hour each on the front two wheels and it barely made a dent but I'm sure about 10 applications it would be gone. On another set of BMW wheels I had to use about 15 applications of megs...
I guess I'll try it on a d/a but I usually hand apply all my sealants and waxes if I'm not in a hurry and never had any dusting like this with others. I barely used an ounce.
I think so too. I had 3 2oz samples I put together in a 12oz bottle but I may have just contaminated all of them considering the dusting is not common.
I finally had the opportunity to try out my wdgps 3.0 samples and got extreme dusting after removing. Prep included clay and Meguiars Ultimate Polish and hand applied wdgps lightly all over the car before waiting 30min to remove. I used about 1oz on a S550. I used meguiars supreme shine...
