If you're talking about the whole length of the shaft then I can't think of anyone personally...and I wouldn't recommend it either...just use sanding sealer once or twice on a new shaft...

I tried it on a couple of shafts a few years ago. It made the shaft very hard so that it resisred dents and although they were very smooth, they still had a drag going thru a closed bridge, similer to a fibre glass shaft.
