    No, do NOT go rotary without plenty of training first. If you think DA haze is bad, wait till you see what a rotary can do when things go wrong. Yeah, you'll burn the paint and the only thing fixing that sort of mistake is a body shop when they repaint the panel. Rotaries are incredible tools, but the learning curve is long and steep.

    I was afraid you'd say that! It is a pro level product after all, and those guys are working all day every day with these products, hence the gallon sizes!!

    By all means give Ultimate Polish a go, but I'm still sort of leaning toward 3-In-1 as the "killer app" for your car.

    Oops.
    Hi mike, the Ultimate polish didn’t work. It just got worse but now a three inch square. Tried it by hand with both the yellow and a microfiber. Maybe something without white abrasives? Like a cleaner wax? The black wax was not able to lift it this time.

    Go with the 3-In-1, that will likely be the best bet to cure your issues. I'd use the yellow foam with the DA Power System you have. Oddly enough, working by hand can actually be more difficult than using a tool, even one as basic as the DA Power System.

    Thank you Mike. Been messing with the Black Wax (DA with yellow pad, micro-fiber, work time, speed etc). The Black Wax did remove the UP square of white haze with the micro-fiber pad, drill DA and just patience, working it. It seems like if the temperature was a little warmer that maybe the Black Wax could work the UC DA Haze out with the micro-fiber pad and the Drill DA. The yellow pad was causing even the Black Wax to cloud but was able to work it off with the micro-fiber pad. The Black Wax is sooooo mercurial looking and smells good. The clearcoat just ***** it up, like healing lotion. Kinda like putting coconut oil on dry skin. I even figured out how to get the swirl marks and 3000 grit sanding out with the Black Wax. Black Wax seems to be this BMW's face cream. Maybe Megs needs to market it as "healing lotion for dry clear coats" and not call it a protective "Wax" as it just fell off with the snow the other day (needs a spray wax topper like UPW or Beadmaker, which is OK considering the clearcoat healing properties and mercurial gloss).

    The roof of the car is very hazed from the UC . Never had this hazing issue with Menzerna and Klasse on the BMW. I just compared UK MSDS to UC/UP and looked at a video of 3n1 and it's also WHITE which makes me leary of it. The local stores don't have the 3n1. Will have to order from Amazon. Will let you know.

    Uploaded images of hazed hood after UC. Tried to remove with UP. Marring would just **** up the UP white abrasives and embed. Used Blackwax to remove a lot of it. Shine and gloss is from Blackwax with a microfiber pad and drill DA.

    Additional coats of Blackwax were then applied by hand and topped with Beadmaker.

    Possibly others will chime in.
    It is difficult to tell from images and there are any more experienced folks than I on this forum.
    This looks a lot like the beginnings of clear coat failure, that I saw on my 9 year old daily driver that parked in the California sun.
    I hope I am wrong.
    Possibly the CC microcracks are being filled by the oils in the black wax.

    This is an image of a vehicle that is showing a little more than the first hints of clear coat failure.
    I hope for you that it is not CC failure.

    When using microfiber pads, the longer fibers work to provide some cut. Depending on the paint, you may get haze from them, that you might not get with a foam polishing pad.
