(like the classic aston ones) my plan was to use RTV silicone to produce a resin copy of an existing cap i have borrowed and then use that to form sand moulds to cast with. my reason for making a resin copy is that it will need alteration (hole filling in etc.) before i can make the sand mould. what i would like to know is is rtv silicone and casting resin the best way to achieve this is there anything cheaper than RTV i can use as I'm on a tight budget and have calculated i will need 5 L of RTV to achieve this any info or advice would be much appreciated thanks
