Last year when I came to work on some seasoned shanks, one or two had bad cracking on the cut ends. I have them stored outside but under cover in my log store so not in direct sunshine either. What do you chaps recommend for sealing the ends as an inexpensive sealer please? I know latex paint can be used but I can't buy that locally here in the UK. I also plan to use a little boron treatment to keep out worm, that I also found in two shanks as well.
