Vinegar or even pickle juice will dilute the smell and they will not stain your clothes like tomato juice. Vinegar has the same acids the break down the smell.
Skunks have scent glands if you shoot one and hit a gland then you release the stink. That why when they get hit by cars the smell is there and powerful.
That smell will last for days and remain on your grass, rocks, shrubs for days.
I have a 357 and a 38 so it would have made a big hole in the skunk.
beside you need to have as much of the head for testing.
If you suspect one is rabid and it dies before you get it to the vet or its over the weekend put peppy in the freezer to keep him from decomposing. Shalom
