I need to shave the third brake light on a doge ram. What would be the best way of doing this? I was thinking about leaving the light in there and using metal bonding adhesive to fill the gap after preping the light with a roloc and grinding the roof area down to metal. Or attempting to cut a piece of metal and gluing it in with metal bonding adhesive. I'm scared to weld on this roof because it is paper thin. Please let me know what you guys think.
