had no idea storm wasn't true surface prep, I just always assumed their overstocks are just strong and aggressive.
I think the word "true" is being bastardized a bit here, somehow inferring the resulting surface is illegitimate.
Skipping grits is simply a different method for surface preparation. It's not necessarily better or worse. For those who refresh/resurface on their own, try both approaches. See what works better based on the conditions you see. Or use both methods at different times to achieve different goals.
When I bought my own spinner several years ago, I went up through the grits (without skipping) like most others. What I found odd was that the OOB cover from the factory usually seemed to have more surface (lower grit) than the final finish I achieved.
When I experimented with Storm's documented procedure for skipping grits, I got a truer replication of OOB finishes and reaction, regardless of company.
Again, neither method is right or wrong. Just understand what you're trying to accomplish.
