Hello neighbor (we'll sort of. Closest I have seen on this site) While I have not done tons of casting I have successfully used epoxy from
the epoxy resin store. I have bought it both on
Amazon and directly. I will double check which type I used when I get home.
I double checked and I have used the general use version.
The good.. it's cheap $85 for the two gallon kit. Have had zero issues the pigments I have tried so far. (Mica powder and alcohol inks). It has adhered to every thing that I have tried it with.
The bad.. it is slow to set up. I leave it in the pressure pot a minimum of 24 hours often longer. I struggle to get much color separation. It does not take thread well or at all.
The company recommends max 1/2 inch pours. I'm not always good at following directions and have poured 2" blocks successfully but it takes even longer to fully cure. I typically wait about a week before cutting and turning.
I am certain there other "better" products out there. But it all depends on what you are looking for. I was looking for dirt cheap to experiment with techniques and crazy ideas that popped into my head.
If you have any questions or would like to see some of the results let me know.
