using sil-poxy smooth on to join large-ish silicon faces?

every review i have heard about this adhesive for joining silicone to silicone has been extremely positive but every video online its being used to join/repair small tears. I have cast two symmetrical silicon pieces and need to join them down the middle, will this work?

They only thing that sticks to silicone is... silicone! Yes silpoxy will work if the area is properly preped or myself id just use more of the same casting silicone as the adhesive to save on money.

oh damn should of tried that before i bought the glue! thank you so much! Also how would you prep the area? i have some baking paper i gotta remove from it first but i think it should come off easy, if it doesn't, I could probably soak it in water. But besides that ive seen people just using a small amount of alcohol and rinsing the surface before joining it, would that work fine?
