Just cut repair patches about 1/2" to 1" bigger then the tear and apply with covering iron. Tack one side first and pull tight (if safely possible) as you tack the rest of the patch. Then run the iron over the patch to complete the process. If it gets to soft, and starts to stretch, let it cool and repeat.

You don't need to strip the whole wing or V-Stab. As what type to use, whatever matches your current covering color, TowerCote is inexpensive or check you LHS.
