The ratty old Lucas horns cleaned up really nicely. They even work as I figured now was the time to check that in case I had to grind out the rivets and rebuild them. What awful sounding units they are, I’ll post a video later.
I ended up painting them black and being a cheapy used some old black appliance epoxy on them. Big mistake! There’s no doubt this paint will be tough, its high gloss and looks good but I’m finding that it doesn’t cover intricate areas well. These horns really need one more coat. Anyway, good enough for now.
