Rotary help please!

I just recently purchased a dw849 and this past weekend had the pleasure of trying it out finally. Polishing with a DA is not a problem for me but polishing with the rotary is. I bought the dewalt and as a surprise my parents purchased the Megs So1o kit for me (#86, 7 in wool and foam pads, and the prized megs hat.) I tried the Megs yellow polishing pad with #86 on my moms Matrix's hood. I know it is probably a no0b thing to ask, but how quickily is this stuff supposed to turn clear? I dont know if i was just using to little product or too big an area, or any other stuff, but I couldnt work the polish at all. I dampened the pad with #34 first, then I applied a line and picked up the bead and I also did the 4 pea sized blobs on the pad starting at the slowest speed of the dewalt, both of which only yielded a working ability of one swipe with the rotary. The pad would then start to stick and the buffer started "grabbing" and "jumping" around with areas of the polish already clear (with not even working in the product.)



I dont know if this is a factor, but when I did take the pad off the surface of the paint, it was still cool to the touch (no warmth or anything at all.)





If I spritzed just a small amount of 34, it made the polish last longer to work it (but the subsequent splatter left me looking like i was ready to go through a saw at a log flume.)



I then moved up to Megs #82 on the dark grey/black pad, which lasted a little longer then 86, but but still fairly short compared to what I have seen others do. Sorry for asking such an amateur question, but I want to master this machine before it masters me.
 
Sounds like you are not using enough pressure on the rotary. This is a very "gray" area for rotary polishing. Personally, I don't use too much (like my dealer who has 25+ years experience with BMW paints and knows the limit). I tend to use a lighter pressure and work and area until it's complete. If I still see some scratches, I apply a bead of compound and go back over that area.



How much pressure is enough? Beats Me!....but I run the rotary at 1,000 to 1,200 rpm and apply enough pressure to change the pitch of the rotary motor's sound.



And I only work a 2' x 2' area.



Try that...once you get the hang of it, you'll be amazed at the results.



Finally, if you are using the Meg's So1o backing plate with the pads, remember that plate has a foam core for additional cushion.

Toto hit on what I would suggest i.e. close down the work area to no more than 2 x 2. My experience when I started using a rotary after what I thought was after mastering the PC included the same things you experienced. Eventually you get the feel for it and you're on your way!
 
Ahhh, Ive been so afraid to push down, but i guess its needed to push product out of the pad. So by applying a little more pressure i should also get a little more control too?



Edit: I am embarrassed to say this, but when I did try using the dewalt, i halogrammed my car pretty good luckily the PC saved my but again.
