I'm relatively new to leather industry. At work we use two component glue which you mix, apply to leather and the other surface, let it dry and then with a heat gun reheat and cover the thing with leather. I would like to have similar fun at home but can't get the glue from the workshop. What is this glue? Or can I get one with similar properties that is already premixed and doesn't go off/lose stickiness after few hours? Where could I buy it in the UK? Thanks
