you really do not need to use a buffer with any product your using.
except maybe the meguiars step 2 which is a polish.
and using a cleaner wax is really unnecessary. and your kind of defeating the purpose. a cleaner wax is kind of like an all in one type of product.
when you use the meguiars step 2, polish your removing the wax that was put on in the previous step.
loose the zymol.
you can use meguiars step one, which is a paint cleaner, then step 2, and then a good carnuba, the step 3 meguiars carnuba will work. i have good success with the meguiars 3 step. for something you can buy at your local autozone its not a bad product.
and claying is not an every wash type situation. examine the condition your paint is in and go from there.
plastic bag over your hand and feel the paint.. if its ruff youll probably want to make a run with the clay bar.
also get your self a grit guard for that bucket, and ditch the microfiber sponge, get something with a little more nap to it, its more forgiving and traps more in the fibers deeper less harm to the paint.
and make sure you rinse that thing out after your done real good.
and grab another bucket and sponge for severely dirty areas.
if youd like some suggestions on some higher end products id be more than happy to elaborate.
