We have rarely used hard wax release systems in the past 20 years, occasionally using TR and mirror glaze in this time. We moved away from hard wax systems many years ago and over to the Chemlease liquid sealers and release systems. I have no issue with any of the products mentioned however we have recently manufactured some boat hulls from a customer mould that had seen better days. The release system chosen by us in this instance was Mold Magic by Grignard.
We had never used this system before now and was totally blown away at how easy the hulls demoulded considering the mould finish. Could this also be one of the cheapest hard wax release systems available. It was certainly the cheapest we have ever bought and find it hard to believe that we had never used it before.
Just thought we would share this with you.
