Rez is bang on with his reflections though on what I used for Toms’s red set, as well as the bullet encased brushes, Rubberset clones, and other casings and scales I’ve made.
Alumilite is a urethane and comes in various hardness and ranges of opacity from water clear to solid color. Also offer cool metal brush on treatments that can be applied to the mold cavities prior to casting to give bronze and pewter type effects.
Super finicky as far as both exact measures of parts, and complete elimination of bubbles. Can always grind up failed castings to add as filler to solid colour works or crazy blends later. I throw none away.. hehe.
Air curing would probably result in a more pliable end product due to the lack of pressure as opposed to the pressure casting I do. But so far it looks like Zak is having way more success than I did before I started employing vacuum and pressure.
The more I look at this project, the more I suspect a Harbor Freight pressure pot is in my future. Looks like lots of folks are successfully using these for castings.
