after applying wax sheet to the part I applies some wax release hoping after several wax applications and polishing i will apply PVA but for some wired reason the wax reacted with the sheet and caused it to become sticky and gummy which ended up messing the smooth texture of the wax sheet , has anyone had this experience and how did they overcome this issue, lastly maybe my work flow was flawed in a way and it will be great if you could point me in the right direction and share the correct steps you follow leading to a perfect mold. 

1: Apply wax/release agent to the part/mould ( I use EC Easylease)
