Longevity is always something to keep in mind with customs. I don't think anyone is honestly sure how well they'll hold up over the course of tens or hundreds to years, but I do know there are certain things we can do to help them last. Some, such as maintaining them in a climate-controlled environment as much as possible and avoiding sudden temperature extremes are the responsibility of the collector. But others are the responsibility of the artist! These include things like roughing up plastic areas before applying epoxy to them, so that the epoxy is able to make a firm bond, and drilling a small air hole to reduce the possibility of bloating if the piece is exposed to high temperatures. I have heard that customs in which these few simple guidelines have been followed are much more likely to hold up and bring joy for many years to come!
In Maysa's case, I scratched up the plastic all over the original (after I repositioned him) with an Exacto knife, making hatchmarks and deep scratches to give good adhesion. Her air hole is tucked discretely in her groin--much less noticeable than the corner of the mouth or the nostril, where many original finish plastics have their hole!
