detailing question (using RO polisher)

[Konstantin Bogach]

I am preparing to polish my cars,  first time,  very nervous :)
   I bought a Porter-Cable unit (7424),  6'', with 2 thick foam pads.  I 
could not find  answers on the web for the following questions:

1)  Should I put a bonnet(terry cloth)  on the foam pad when 
cleaning/buffing? 

2) Can I use RO polisher to buff the haze after applying wax (manually)?

I would appreciate if you could answer these questions.

Thanks.
Konstantin.
