I would like to cast some parts like periscopes, dome lights, service lights, googles, etc

Anyone know a resin that casts clear?

TIA

Alumilite (spelling) has a crystal clear resin they sell on Amazon. It is very clear, can be tinted any color and can be polished to be as glossy as any styrene part. Your master will need to be of a glossy item so that your mold will produce glossy copies. Think of those bugs that are encased in a clear block. That is a type of resin and is as clear as any glass. I hope this is helpful information.

So you have to prep the male with something so it will leave residue in the mold? Does the master have to be clear?

The master doesn't have to be clear nor do you have to have a release agent, but a thin film sprayed over the master wouldn't hurt. The main thing you will want is to make sure that the master is polished to very smooth and glossy finish. Any surface imperfections will show up when the clear resin is cast.

Okay, might be a bit of a challenge on some objects..

I have cast a few clear items in both urethane and epoxy resins.

I don't know what others experiences are but I found that if I didn't vacuum or pressure cast the clear resins, then bubbles were a major issue. I should note that I was casting some quite thin parts, 1/9 scale sunglasses, so bubbles may not be so significant in the items you are casting.

When I faded out of modeling, PE Brass and resin wasn't being used. With that said, I want to get what input I can so I don't get my hopes to high about the end results. I don't see myself trying to make Wonder Woman's plane, but, the problem you stated with thin parts may very well be the road I am going down. I had thought of using resin clear for 1/35 goggles, but 1/35 periscopes on a m113 will be pretty thin even though I want to cast the whole periscope. Somewhere on here I saw a article on air pressure castings, I guess I need to go find it.
