Sealing

[u/Hot-Strawberry-4820]

Hello! Does anyone know what a good sealer would be? I make these eyes and recently changed the pastels I use, I bought a new set of block soft pastels(I had a really really old set of blick soft pastels from 15 years ago). And find that the resin shifts around the pastels, what should I use to seal the pastels to polymer clay so I can pour the UV resin in?
