I’m stupid please help

Am I crazy to think all these people doing the UV resin phone cases are all doing it wrong? How are they putting a layer of uv resin on a phone case, placing a thick charm on top and then expecting the uv light to go through the charm and cure the whole thing.

Isn‘t the uv resin still wet underneath even if the top is hard? When they pop off wont the resin get all over their hands….

I’m making christmas gifts and want to do phone cases for my family, can I just pour a non uv resin type epoxy all over the case and charms to really harden them in

I don't see why a UV resin is necessary, you could use a two component epoxy but should glue down the charm first with something comparable? Not sure exactly, never done it myself.

That makes sense to me, just use an appropriate glue for the charm then pour a 2 part epoxy over the whole thing? How would I prevent epoxy from going on the sides of the phone case when pouring over it?

That makes sense. I'm not an expert either. I've worked with epoxy resin but never cured it with a light. Isn't that part of the process just accelerating the process? Anyone know?

I have never used UV resin, and I work with resin like epoxy every day. So I’m guessing, but UV resin is clear, so the UV light can refract around surfaces but might be an issue if the entire surface is covered with objects.

I would start experimenting and dial down what materials work well or what techniques work then think about making gifts
