Hey guys my is brian from vine grove ky.Today i had a delivery made and the truck when pulling out stripped some bark off my tree an area about 8 to 10 inches in length and 6 to 8 inches across with no damage to the wood underneath as a repair they put a roofing sealer over the area, now i'm worried that i've let them do something that will kill my tree have i or is there something i can do correct what they've done before it dies or is harmed to badly to save.Thanks Guys Love the Show,Brian
