I tried it with clay impressions years ago. It was kind of a crude one-shot attempt just to produce a plastic replica.
With the Evinrude emblem I just made an impression in clay and then poured some kind of liquid hobby plastic in and let it dry. When it was cured I removed it from the clay and sprayed it blue and stuck it on my dash in the boat. Its pretty weathered now but has held together for 10-12 years. It just needs to be repainted with more care.
For the Johnson Sea-Horse I pressed a "slab" of clay on the side of the housing of a ’54 Johnson 10 horse, slowly lifted it off, and poured plastic in the impression. I can’t remember what the name of the plastic was that I was using. These were more just hobby projects and not full blown reproduction attempts with serious materials. I think I just wanted to test and see how to and if I could do it and save it for another day (or year).
A while back someone did something similar with a Mercury front cowl emblem that came out beautiful. I think he used a clear epoxy and a UV/fade resistant picture…I think. Maybe if he sees this he can post it again. It would be a nice technique to use for the 58 Johnsons/Evinrudes.
