About a year ago there was a post asking how to install their F shields indented in there fiberglass fenders.
I installed one of mine yesterday and thought I would share the process.
Before you do any cutting. plan where you will be placing your shield and determine if their is enough thickness in the fiberglass. In my case I added a few layers more fiberglass to the back side of the fender where the shield would be. This will keep the integrity to the fender and not cause a weak area.
Mark the area that needs to be indented with a fat magic marker where the shield would be installed. By using a fat magic marker you will be making the cut line slightly larger than the shield. I used an air die grinder with a rounded burr cutter. I started by cutting around the entire perimeter. Until I achieved the same depth all the way around. Which was .115 of an inch. This was the total measurement of the shield itself along with the mounting material combined.
