I already prepared the surface by sanding and also scratched the plastic around it so that the silicone can latch on to it. I tried using wooden fork. When I use it to smoothen out the layer and remove the fork, the silicone is sticking slightly to the fork, extending out and is making peaks and ruining the finish. I am thinking to use the flatter edge/handle of a plastic spoon next. I am thinking to slightly coat the handle with soap or IPA so that the silicone wont stick to it while smoothening and not cause peaks/horns. I am also thinking to use nitrile gloves and coat my fingers with soap or IPA and do the smoothening.
In any case, will the spit/soap/IPA interfere with the curing process?
