If you want good quality woodgrain vinyl, check your local body shop supplier and check the 3M catalog. They should have it, and it will be of excellent quality. 3M isn't cheap, but you know that whatever you buy from them will be good quality.
I searched for striping tape, pinstriping tape, stripe tap, etc. The one guy I have used before , I bought from twice, and referred others to can be emailed --Leroy Peterson ; email@example.com
He sold me 150 foot roll of very high quality tape, more than enough to do the AS twice.
