What can I use to seal the limbs after I trim? I have always used good exterior house paint, but now I'm wondering if it's harming the trees.

No evidence at all. Some paints can deter compartmentalization leaving the cut open longer than if not painted. In areas prone to oak wilt it is recommended to paint cuts but pruning at the proper time of year is much more important. I use Lac Balsam for esthetic purposes only.Is there any evidence painting over exposed wood on cuts will prevent borers from entering? This is after the tree has healed over the cut on larger limb removals. I was just curious since borers are starting to do a number on the oaks in my neighborhood.
