I have a porcupine to do from Africa. What type of tan would you use a submerge tan or rub on. I have been using Pro-1 products, but am open to to what would work best. I have a idea on what I am going to do, but would like to get some more input. This is a personal animal ,am i am not a newbe, been doing this for 44 years, but i have not tanned any African, and the taxidermist in Africa who did the dip and pack said they are very difficult to handle. Any info would be much appreciated.
