Like a lot of finishes there is more then one way that it can be applied, just because one person applys it one way doesn't make any other method of application wrong, just different.
I've yet to read any finishing method that replicates the way I finish my pens, I've been doing it my way for years & am happy with the results & longevity of finish but I don't presume anyone else's method is wrong, just not how I do it.
That said I'm always interested in reading what others do & am always happy to try other things, that's how we learn. Keeping a positive open mind is the key.
