In thinking about shortening the distance between the brow trim and the eyes to closer to a 1/4 inch, which is in the description for the CRL Level 2, I came across some rubber edge trim. It was the right size to cover the brow trim the helmet came with, and it didn't force me to rebuild the edge of the helmet for an entirley new brow trim. The edge trim I purchased is also closer to the width of the brow trim in the gallery images.
I purchased the rubber edging and then measured and trimmed it to fit the helmet. The longer side covered the wider, visible side of the brow trim. The short side covered the underside and also covered some of the overspray from painting the helmet.
I used a small amount of J-B Weld to glue the new edging over the original brow trim. I did it in three sections. My magnets wouldn't hold through most of the trim so I used painter's tape to keep the new trim in place.
The change in size is not overly noticeable, but there is enough of a change to make the distance between the brow trim and the eyes closer to a 1/4 inch.

The exterior of the helmet is now complete for Level 1. I will work on padding and possibly adding a chin strap next.
