I want to now if any of you make resin molds? I think the muscle machine cars would be great for a zip zap. I dont now about all of them but I now the bubble top 62 wheel base is the same. Id love to have it for a body but dont want the metal. Id like to do resin but dont now much about it and dont want to spend 70 bucks for a starter set. Anyone make these or now a cheaper way to get started in it?
