How To Repair a Tear On a Silicone Sex Doll

Order a silicone glue: https://www.amazon.com/dp/B0002UEPVI

The glue is clear in color. If you want it to be the color of the skin, order the pigment: https://www.amazon.com/dp/B0C1NDMSF9. You can add it to the adhesive to color it, but you need only a tiny amount, a pin head, no more. Try mixing it in a separate cup first. Alternatively you can use makeup powder to color the adhesive.

INSTRUCTIONS

The translucent silicone adhesive is used like glue but it needs to sit for 24 hours undisturbed to fully cure. Thoroughly clean the area to be repaired with acetone or isopropyl alcohol and apply only a tiny amount to the cut and find some way to hold it together while it cures. Unlike most glues, it won't be able to hold anything together itself until it is set.
