You could, or you could add some aerosil to your mixture to thicken up the resin you do have. We get a lot of marine/canoe builders that figured out different work arounds so you don't have to buy multiple resins.

Hi everybody! I have a question for you. Witg application in moulds with vertical walls, is it necessary to use some thixotropic epoxy resin or can I use a standard one? Thanks
