I just found a great deal on the ever so hard to find gum rosin. I just got my order of 55lbs in a nice round container a few days ago. It was delivered by Fed X for a total cost of $112.50.
I bought it from Mann Lake the first time but this saved me around $40.00.

The website is http://pdmchemicals.com/
Just call the 1-800 number and tell them want you want.

Here are some pictures of my hive dipping operation.


I hope this is helpful to everyone.
