Restoring JBL Fiberglass Horns
Reference thread: http://www.audioheritage.org/vbullet...s-and-brackets
Pictures before and after in order, and beware there's a lot of elbow grease involved. I tried some mild paint removers but it was damaging the fiberglass. Ended up wet sanding with 320, 400, 600 and 1500 and then polishing with some Meguiars polish for plastic headlights. Later I'll fix the corners, sand with finer paper and use a fiberglass specific product (check out boating restoring supply web sites). I happy, so instead of looking like trashed horns they look like taken care of JBL horns!:)
