Just to make sure I am not out of touch here.
I remember way back in the day that we jumped back and forth between pruning paint and not. It is my understanding that the standard is to not paint, did I miss another change?

There is a product called "Lac Balsam" I was told it is used in grafting, the tube has a brush built into the end of it. I was told it was acceptable to use this to "treat" wounds. Not sure if that is still true, its been some 10 or 11 years sinse I learned this.
