dont know the guy (strunk)
cant say i even know what his wrap looks like
however if he truly did come up with a certain style
and was the exclusive user and there fore it became his "known trade mark"
i dont see a problem with him not wanting it published on the internet
especially if has taught others how to do it nad gave them permission to pass it on on a one on one level
i have a lot of tricks ive learned over the years as an auto tech to make my job easier
do i tell all the newbies how i do things to make myself faster/better
hell no,let them learn
i do give advise when asked and thats how i keep it
one on one
