I have used shellac a few times on both cotton and cork tape and while I wasn’t so keen on the resulting texture on cork tape, I absolutely loved it on cloth bar tape. It’s a great way to extend the life of your tape, add texture and really tie a classy build together. Hokoge on Flickr has two quality examples of the resultant look of shellac on a track drop and townie bar. Check out his Flickr for the full bike. It’s a lovely one!
