the vented wheels are pleated so the face is rippled,(check caswell's site they have them). it is said to be cooler running and holds compound better. it came with the machine when i got it. its true i get a great shine with the black, as for how, all i can tell you is it starts out hazy when i use the cut motion(wheel spinning towards me part on bottom of wheel working upwards to me) then i switch to a side to side motion(move part left to right and from bottom of part to top (color motion) keep in mind that pressure and heat play important roles in the finish you get. try to press harder or less and change the movement you use. as for the drill i do not use one yet as i got a stand buffing machine(1.5hp,3600rpm). as for the scratches are the parts alum? if so dont feel bad i have not done a perfect scratch free part yet, and there are many posts here about this problem. when i say that i mean it has micro scratches when held in bright light. this is what all of us battle. also remember to rake the wheel often. if it starts to shine on the face it is loaded and needs to be raked. hope this is helpful and as always best of luck bro.
