Here's how I did it. Not difficult. A little time consuming but worth it. Paint the entire cowl 1/2 the lighter of the two checkerboard colors (in my case white). I then spayed on 1 heavy coat of Bob Dively liquid mask. In my opinion, the heavier the better even if you get a few runs. Draw the checkerboard pattern with a fine tip sharpie pen. A flexible drafting ruler available at arts and crafts stores helps here but is not necessary. Cut out on the lines using a #11 exacto. Pull out every other sqaure. Paint second color and let thoroughly dry. Peel out remaining flex mask. Please feel free to email me with spcific questions. cbk
