hi m287j
dublin wax u can usualy buy from any shoe shop etc or where leather goods are sold
it helps to protect leather keep it water resistant and flexable to reduce cracking and drying out when you rub it on you pay attention to getting it in the seems and welt lines of your boots its also good to use on motor bike jacketts and drizabone coats etc think the last can i brought was about $12
it real dose help prolong the life of your boots ...
