I don't think this product will fill in the gaps for Abralon users. It's sometimes a little confusing with the different standards of grit.
There info says it is "micron" graded and Abralon is "P" graded.
When I look at the bowlers grit comparison chart I get confused by this. The chart says, the higher the micron number, the coarser the product is, this I understand. At Rockler's site it appears to be that the higher grit is finer, but they mention it is micron graded.
To avoid all this, I use "P"graded sandpaper and "P" graded Abralon and try to fit in the U.S.(ansi)graded compounds. This works good and keeps things clear.
Thanks for sharing.
