ive had someone suggest using ca over rawhide for a finish, they said it turns out very well and is smooth as well as durable. ive also seen it used on snakeskins. my personal opinion is that the labor involved in sanding it clear enough over wood wouldnt be worth the exposure to the fumes given off. in knifemaking i only use it for minimal pieces such as bolsters/end caps or spacers of diferent materials. i have, however also used it to seal handle wraps of hemp twine.
