Might be a bit off topic but I got a few questions. I'm doing a restoration of my IJ. I started tumbling all metal, tumbling, polishing and clear coating the coil brackets to protect them from corrosion, cleaning all coils, installing new parts everywhere, ect. I came across this coil bracket that has a piece of insulation. I removed it since it was in really bad shape. The manual has a part number for it. I tried several vendors with no luck. Is this insulation really necessary? Could I just use some Mylar instead?
I mentioned that I've been cleaning and clear coating metal brackets for protection. Should I spray some clear coat on the ball trough assembly? Is it in danger of getting corroded if I don't clear coat it? Seems to me that the balls will eventually remove the clear coat from the ball trough assembly and spread it all over the playfield. Also considering installing the ball trough protector seen in the pic. Thanks!
