Plastic resin question...sorta O/T

Ok guys... When I was in high school we made these resin lightbulb paperweights out of a clear plastic resin. I remember tinting mine blue and it was still transparent. We took household bulbs, wrapped them in masking tape, sanded a small hole in one side and poured this two-part resin into the bulb.
Question......
Does anybody here know what this stuff was? Where I can get some? Any brand names? What tint to use?
It's for the "Ultimate Camaro" project, just had a brainstorm and can't remember any details on this product...
Any "shop-class" attendees know? Or do you all build computers these days? LOL
(damn, I'm old!!):D

i think its called castin craft clear. its with the plaster, glues, near the clays. got mine at michaels. two sizes.. $8-10. and then you have to get the catalyzer . they had like 4 different tints you can buy and add.

but normally its clear.

THANKS!!
I'll be there in the morning!!:D
