Spoiler templete or tricks?
 

Are their any tricks or templetes I could use to mark the holes for my spoiler?

Thanks.
Matt

don't know if you still need a reply....
I used contact paper (for lining kitchen cabinets, drawers). Mark the side with the pattern, peel off side facing down, so when you pull off backing you can put it on the car (doesn't hurt paint, peels right off). Works great.
