I needed these old Caddy valve covers from the heads of this old glue bomb engine I had for a build. I couldn't separate them so I just cut the heads off and sanded the material down to recover the set.
After getting the valve covers ready to install I remembered that these were the only pair I had so I decided to make a mold of them for future use.
I started by using white glue to secure them to a piece of index card.
While I was at it, my original built up Blue Beetle arrived so I thought it would be a good idea to mold those heads too.
I built up a mold box with Lego blocks, again glued to the card with white glue with the book to hold it all in place until the glue set
Time to pour rubber, I like this stuff. I follow the instructions to the letter.
Time to pour some resin. I like this Micro Mark stuff. Again, following the instructions to the letter.
Mixed 1:1 and poured into mold
After about 45 minutes, it turns white when cured
And popped out of the mold. Just need a little clean up and they're ready for prime, paint and Alclad!
I use a little extra material to prevent what is illustrated here in some of my earlier efforts. Perhaps overcompensating a little but as you said "to each his own" and that's my own.
WOW... I never seen molds do this! I'm not here to tell you your business, but I've made over 300 molds with Alumilite RTV Silicone, and never once have I had a mold warp like that. What you do is your business, but you might want to consider another brand.

Thanks for your advice, As I've said above... I have solved this potential problem for me by adding a little extra material to my molds. It's all good and it works for me. As you can see by the colors they are all different brands. I am happy with the one I use now. BTW I don't do this as a business at all, just to make a few parts for myself or from time to give some away to friends. I posted this just to encourage any other modeler to do the same by showing just how easy it really is. Thanks again.
Nice work! Those turned out great. I'm going to try this one day. FYI, if any of you guys get to looking for these parts check one of the 3n1 re-issues of the 59 El Camino. Not sure if they are exact but pretty close. Thanks again Ron!
Micro-Mark resin is simply repackaged resin made most likely by Smooth-On. I get all my resin molding supplies (RTV rubber, resin, mold release agent and dyes) from either www.smooth-on.com directly or from www.alumilite.com . Each brand is similar, but different enough to be used for some specific task. bare-metal.com/ also sells casting resin and rubber mold material.
