66 Impala Tachometer Identification

[SuperNovaSS]

Well, multiple people told me not to try to clean the tach face. After thinking to myself, "What would NJSteve do?", I took that as a challenge and went for it. I tested the gas gauge first by dusting it off and spraying it with Windex. When the numbers didn't wipe off or smear, I figured it was worth the risk to take the tach face off and dunk it in the Evaporust.



Here is the tach face removed and placed in a Pyrex dish so I could periodically heat the liquid on the stove(it works much better warm).













Then, in goes the Evaporust.





I kept the liquid slightly warm and checked it in about an hour. I used a soft paint brush to wipe the gauge face and see the results. The rust was going away but it needed more time. I see no ill effects of the Evaporust at this point so I dunk the face back in the juice. I let another hour go by ad checked again. At this point I was happy with the results so I pulled the face out and rinsed it off with water. I then blow it off with low pressure compressed air and this is the result. Another hour probably would have removed all the rust staining on the numbers but I didn't want to risk paint flaking off. It should look great now when it is mounted in a cluster and is behind a lens.
















I just thought I would share.


Thanks,
