In Your Spare Time
Here's a small job that will make your bus last longer. If you find it of interest you will need about one and a half hours depending on how hard you work at it.
I wanted to polish my blemished license plate mounting casting and after thinking about it I thought it would be better done off the bus than on, so off it came. Whoh what I found behind it. Packed in the space between Aluminum and Stainless was a crusty mass of dirt.
There is no place for dirt like this on any bus. I brushed it out and washed it off and found corrosion by electrolysis.
I knew that if I put it back without doing something it might not last long enough. The casting is only about 3/16" thick.
What to do?
First I polished the etched SS and the Aluminum casting, can't have any of that on a proper bus.
Next I wire brushed the inside/back side of the casting and painted it with Zinc Chromate primer to help prevent contact of it with the SS.
Next I applied Electrical tape to the SS surface that would make contact with the Aluminum and to the under side of the mounting screws.
Finally the assembly went together and I have all the confidence that it will now last at least a lifetime.
