, when you do the remolding wrong.expect the tear to reappear.
I would go even a step further and can tell you, remolding a brand new doll's head and private parts went to no tears at all just because of erasing the predetermined breaking points
As design engineer for molded plastic parts I wondered about the crap I found as a newbie; and it teared as feared.
I would never adopt a new TPE doll without remolding her as first step after the hundreds of them I've seen here on the forum and expected them to tear very fast.
Don't get in contact with this toxic stuff!Extremely important!!!
Work in a ventilated area!!!
Never breath it in and don't touch it heated!
I don't know a manufacturer who tells customers how many % of which toxic substances are molded into a doll.
