I definitely have a strong preference for wrapless cues and have been
giving my old cues with wrap similar treatment only what I do is to
get the best oil based clear coat high gloss lacquer at the Home Depot.
After about 3 coats, light sanding in between, my linen wrap cues have some
of the sticky feel of the wrapless cues.
What a mistake - FOR ME - to have bought all those wrapped cues.
Anyway maybe I should try what you're doing on one of them.
On a few I tried to get the stickiest leather wrap available but never liked it.
Wrapless all the way for me.
