What machine is going to run those pads? Rotary or Random Orbital ?
On a rotary, I have had great results using the Lake Country Hydro-tech Pads and those products you listed - however, these Pads are more fragile than I care for, and will break down and start separating way too soon. They cannot even be cleaned with Lake Country's own Pad Washer either, because it also helps the pads to break down too soon.
These pads have been out for over what is it, a couple of years now(?), and I have not heard one peep from the Manufacturer about improving the product, so that they last longer..
On my Random Orbital machines, these same pads work great too, but for me, take longer to correct, so I only use them for small places, bumpers, etc..
I have no experience with the new Meguiars Microfiber Discs but from what I read, they are totally great with their own specifically made polishes. Believe some people on this Forum have also used other products such as you questioned about, with great results too..
You can purchase all the products you asked about here, and at very competitive prices!
