The traditional method of reproofing oilskin products and wax jackets is with a reproofing wax which, whilst very effective in restoring the waterproof properties, is hard work!
This spray application oilskin reproofer contains a wax and fluoropolymer which provides a convenient method of reproofing the dry patches that are subject to friction such as knees, sleeves, neck and shoulders. The oilskin reproofer also contains an antibacterial additive which prevents against mould and mildew.
