Best compound to pair with the Meguiars microfiber pads is Meguiars D300. It was created to work with those pads as a system and I haven’t found another compound that provides as high level of user experience and results. If for some reason that combo can’t correct fast enough, then bust out Meguiars M105 and use it with the microfiber pads. There shouldn’t be a paint on earth hard enough to survive that combo paired with a Rupes Markll.
Isn’t Menzerna diminishing abrasives? If so I wouldn’t use that with microfiber pads because ideally you want to keep your buffing cycle on the short side as opposed to a longer buffing cycle which diminishing abrasives are meant to use... If you have the habit of doing long buffing cycles you’re more than likely going to wind up like the people who talk about microfiber pads delaminating and not lasting very long. I’ve personally had the same batch of Megs microfiber pads for over 4yrs and they still work just like new because I don’t overheat them.
Using the brush to clean them is about 40% effective compared to using compressed air to clean them, be aware of that and if your paint is heavily oxidized or in need of heavy correction you’ll need to swap pads pretty often, expect no more than 2 panels before having to switch out to a fresh pad if you don’t have compressed air.
Side note: If you’re stalling try the washer mod.
