I believe pine tar works as an antimicrobial when used with oakum under shoes and repels moisture on the wall. Works well on those issues. Not to mention give you a hell of a good grip on things. If the problem is in the lamina bonds my first choice would be a product like Farriers formula.
Hoping a farrier like Ironbender will chime in with his educated take on the subject - my take on the subject is opinion.
