For scripts and other small details go to the Auto Parts store and pick up a tube of Red Silicone gasket sealer. You can put about a quarter size blob on the detail you want to copy. After letting it dry for a couple of days peel it off slowly. Hopefuly you have a nice negative of what you want.
Then spray some silicone lube on the mold and let dry. This acts like mold release. Then mix up some clear 2-part epoxy and flow it into your mold. Make sure there are no air bubbles. Let harden. Then sand the back side untill you get very close to what you want to keep. Foil or paint and attach to your model with super-glue or clear Elmers. Plastic gule will not work.
F.W.I.W...
