Making casts/molds

Over the years I have made molds of various wood appliques and furniture parts I needed to duplicate. I haven't been really happy with any of the methods I've used so far.

If anyone has any ideas on materials/products they have used and liked I would appreciate hearing about them.

Bondo is the best. Mix up a nice hot mix, spray the item you want to cast with Pam cooking spray (LPS or similar oily spray should work), press it into the bondo and let it solidify. Pop out the original with appropriate tool.

I use Bondo to make fishing sinker molds, I fish a lot of saltwater and make those pyramid sinkers this way. I grease up whatever sinker size I want, set it in the bondo, let it set, and pop out the old sinker. Holds up well to the intense heat. One mold I have has made hundreds of sinkers.
