I posted this in the Women's Issues forum not too long ago. Hope this helps.
I didn't use the Clone-A-Willy brand, I used this: Lifecasting, Mold Making, Molding Materials, and Casting Materials from EnvironMolds
Most of the other DIY kits available (Make Your Own Dildo, Clone-A-Willy) aren't as good and don't allow you to re-use the mold. The Intimate Kit does. You will have to buy your casting materials separately though (it comes with the materials to make a stone-like replica which you can treat with a finish such as faux bronze). I suggest SkinRite10. SkinRite is silicone rubber and used for very realistic prosthetic skins. (It has a shelf life of 6 mos.) SkinRite 10 Special Effects Silicone
The clone itself is pretty amazing. Every vein and ridge, the fat girth, the round curve of the head, even the urethra is there.
The Intimate Kit is like 60 bucks. The bronze finish is like 60 as well (this you would use only if you want to cast the stone-like replica, this material is referred to as CastRite). If you want to use the CastRite you would need to buy a mounting base as well. The SkinRite10 is around 50 bucks I think. Full cure is like 7 days. Of course, there is no vibrating version.
