Kantstik Wax by Specilaity Products in the USA. A silicone free pure carnuba wax that breaks in a new mould like no other! Simply apply and buff to a high gloss to ensure a good release. Work best on rigid moulds llike GRP Fibre Glass Tools. It is essential to cover all the area several times over, failure to do so will result in the mould and cast becoming stuck fast. Works well in conjunction with PVA Gloss.
