How do you bring the Versa max back to box condition and can you substitute an Abralon pad for a Siaair pad?
The instructions given above are accurate. They are on the VersaMax web page.
Yes, Abralon and Siaair use the same grading system, FEPA. So 500 grit created by an Abralon pad will be the same as 500 grit created by a Siaair pad.
To be a little bit more explicit -
I feel it is more accurate to describe Brunswick's Rough Buff as a rubbing compound due to its aggressive abrasive action. It used to be used over 220 grit on many Brunswick balls, like the Vapor Zone. Today, the stock finishing process usually calls for it to be used over 500 grit, sometimes 1500 grit. RB will add a polish-like shine when used over a higher grit, like 2000 grit. (In this sense, it will act like Storm's Step 2 - being also very abrasive, it can polish a ball when applied intensely.) When RB is applied over the 500 grit sanding, the finish appears half-dull, half-shined. While it could be considered equivalent to about a 3000 - 4000 grit sanding, it is not that and does act differently from a simple sanding.
Brunswick polishing compound is called Factory Finish High Gloss polish. This is what is applied after the Rough Buff has been applied to the VM.
