Tempted to propose lots of silicone caulk, pneumatic staple gun and a few hundred staples, and a foot-stomping temper tantrum demanding intelligent discourse from the skunk as you shoot!
The local animal control officer (if you have one) or the services of a licensed trapper might be your safest choice, followed up with a closure method which will deter future opportunitstic occupation, also aking sure the garbage is contained as well (close down the local skunk buffet). Skunks, especially in the late summer, are sometimes found to be rabid; they can also carry other diseases and parasites.
but do you need to tool the caulk for 15 minutes? see that would put you in a dangerous location
