I'm trying to reproduce rubber parts for an antique auto. These small parts, which are basically bumpers, are no longer available so I'm trying to make them but once I form them they have a very rough appearance after cutting, grinding and sanding. Is there any way to make them look like molded semi shiny parts that are available for other cars from restoration suppliers other than to apply a coating of Armor All or similar products which only last a short time?
In response to SkyPilot, first of all thanks for your input, my car is a 36 Dodge. Can't find trunk prop arm bumper repoduction. Also had to shave trunk closing bumpers from Steele Products to get trunk to close. Asking this question also for others I know to see if there is a way to get a nice finish after reshaping or reproducing a part from blank rubber or reproduced rubber parts that won't quite fit .
