Gabriel,

If the lugs could be trimmed on edges only, then that would be immaculate: which would be laying thin tape on lug edge over stripe color coat. My Raleigh dark metallic Green with gold pin stripes after 36 years looks like rust stripes where the gold faded. The clear over powder coat looks better lasting like under acrylic layers. I don't know how many mils thick they paint with single, double, and/or clear layered, but the lug pin stripes would surely gain attention of the lug riders. And they should look that wa y until pollution and sun eat through the clear, which should be a while. I would not even care too much about decals personally, except my badge on front of course.

Thanks, Phil Bailey Sarasota, FL
