After a lot of reading on various detailing forums (and on here of course) I've just placed an order for some Poor Boys Black Hole and some Natty's Blue Paste wax to treat my Panther Black. My brother works as a sprayer/refinisher for Aston's so he's going to borrow a rotary polisher from his work to compound the car first, to hopefully get rid of some of the imperfections. He's leant me his own Rupes DA and I've ordered some new Menzerna supersoft finishing pads for it so I can use it for the glaze/wax stages. (I'll admit I'm no expert so I didn't fancy using the rotary, which is why he's doing that bit and I'm sticking to the relatively safer DA part). From what I've read, the PB Black Hole works very well when applied by DA, but is the same to be said for the Natty's Blue? The DA doesn't have a variable speed, it's just set at 7000rpm. I know if it was a rotary polisher then it would be too fast, but will the way the DA works mean it's ok?
