I found this the easiest.......draw you cutout design on the cowl with a sharpie or waterbased marker...whatever will not hurt the paint.

Take a drill and drill small holes inside of your drawn line. once you have holes all the way around go back with the drill and connect the holes so the center of your design falls out. Next take your dremel with a round sanding wheel and sand to the drawn line. If you have a corner its best to round it vs make it square as a round corner is less prone to splitting.

Then take some rubbing alcohol and clean the cowl (if your paint is not affected by rubbing alcohol)
