I've been using Lutan F to tan all my capes and hides so far and they have all turned out great. I've recently had to purchase a few capes which were all tanned by another taxidermist. They used alum and they turned out pretty similar to mine. Lutan is over 3x the price of alum, so I'm wondering if I should stick with Lutan to tan or if alum tanning is just as good? Are there any reasons why one would be better than the other for taxidermy work?
