Sharktooth grille repair

Yea, the thought crossed my mind early on to make a template mask out of something like styrene plastic. So I got my micrometer out to measure the distance between the fins, and there are hardly 2 that are the same! Weird huh? I figure this was done as a visual effect when viewing the grille at a top down angle or something. At any rate i began masking... I do have X-acto knives and such; I just found more control with the Stanley blade as I also use it as a smoother to get the mask right up to the edge. Thanks all!
