I recently acquired one of my "Grail" props. What finally looks to be an accurate replica of the LIS laser pistol. I've wanted one ever since I was a kid, but no replica looks quite right. But, as you can see, the barrel is damaged. As an added bonus it turned out to be a metal replica. Obviously pot metal though. Wanted to post for advice on how to restore this thing. I started to take it apart and have to fix some minor damage from the disassembly which is mostly at the emitter end.. I have two main concerns. The barrel foremost. I thought I could cut the barrel where the bend/break is then insert some sort of coupler and JB Weld it back straight together and fix whatever seam remains. Then how to clean the rest of the gun. Do I sand it? Wash it? and then repaint it? Any advice appreciated! Thanks!
