Thank you all for the kind response.
I have noticed it does come off easy when applying Mold cleaner and even when it comes to warming it up and applying it on curves, it is not a problem.
The real problem is how the surface of the wax opens cracks when conformed to a curvature and sometimes it is almost impossible to notice it until seen in the mold when its too late.
Even when sanding and polishing the surface comes out poor.
Any suggestions or tips even replacements idea for the same intent would be appreciated. Thanks!
