Then, a longer project. I didn't know if I could get fog lamp lenses, so I planned ahead. Before I cut out the lens holes, I made a mold of the area with fiberglass, which created a reverse image. I don't know why I didn't just use the plugs I cut out to make the holes, but I do remember cutting up the plugs pretty bad as I cut them out. Anyway, I then made positive images from the negatives, cleaned and sanded them, including gel coating and finish sanding, then thermoformed a few lenses. I must say they turned out terrific. I can make more if anyone is interested. However, they are a pretty specific size, so you'd need to cut the holes using the lenses as templates to make them perfect. I used H's fog lamp buckets.

Finished product turned out perfect. How in the hell do you take a photo of something clear?!??
