So, what is the best way to smooth out the thighs of a realistic sex doll? Is it possible to do such a procedure without having to order specialized tools or special TPE "glue"? This actually looks like a pretty effective smoothing method. Larger scratches might not disappear completely, but it seems like this approach can at least prevent further damage. You should be fine, but I recommend testing it on a hidden area (like the soles) first to see how the material reacts.
