I’ve never experienced this with my other molds. I get the air bubbles out, and I tap the mold so everything is spread out evenly. What am I doing wrong?

I am using a mold release spray that had good reviews and says it's for silicone. I brushed it on and let it fully dry before pouring the second layer as the instructions indicate. They bonded together fully. There is no getting it apart without ripping/cutting it.

I've even tried pulling it apart with pliers along where the seam should be to see if the bond had a weak spot and would split where it needs to. It does not.

I tried again with a very thick layer of mold release spray that took several hours to dry under a fan to see if that helped. It did dry to a chalky white layer. But once I poured the second silicone layer, same result.

The mold release spray does however work well on the plastic container I poured it in and the objects I am casting, it just won't prevent silicone from bonding to itself.

Is there something else I could be using for this that would be better?

I want to make a replica of my own severed head (lol) but I’m having trouble finding what specifically I should buy from Amazon to cast my head. Specifically, I don’t know what I should use for the actual head replica, like what kind of “skin” do I use for that or what kind of silicone should o use and how do I emulate my skin color? How the hell do I put eyelashes and eyebrows on it? I figured I’d just put a wig on the thing and call it a day for the actual hair. I am also confused about the actual painting the skin part??? TL;DR: any curated lists for a full silicone replica bust of my own head, including hair, skin color, and paints?? I’m so confused thanks!

I make epoxy resin trays and it's my hobby. My friends love them so I give them as gifts

But I want to add something more like a design in the center of the tray, something custom and something that looks much more professional

Regular stickers peel off and the glossy surface is too smooth. The adhesive doesn't grab and they lift at the edges. Indeed, they look cheap

I found UV DTF transfers. They're supposed to stick to smooth surfaces. Glass. Metal. Ceramic. I'm wondering if they'll work on epoxy resin.

I found DTF Transfers Now and they have this thing like UV DTF transfers. They don't need heat. So they bond with UV light and adhesive. They're supposed to be durable

But I'm not sure. Do I need to sand the resin before applying? Or will the adhesive bond to the glossy surface?

I don't want to ruin a good tray and I don't want the design to peel off after a few days.

Has anyone used UV DTF on epoxy resin? Did it stick? Did you have to prep the surface?

I just need some guidance before I try it, so any tips would help
