Vinyl resists etchant just fine, no need fiddling with masking, electrical, or kapton tape. It is much easier to cut and weed (remove unwanted vinyl) while it is still on the backing. Then apply with application tape just as if it were going on a sign.

Or maybe better yet, bond the tape or vinyl to the copper clad FR4 and then cut. Remove the unwanted vinyl or tape and etch the board. I have not tried this technique exactly, but have done a few boards with hand cut tape. If the etchant doesn't leak under the tape or dissolve the tape, it works fairly well. The trick might be to find the right tape, perhaps Kapton tape, or wide electrical tape?
