I have some alumifoam that I am making some crankbaits out of but am having issues with it to some degree. I molded a crankbait and then added an epoxy sealer coat and it had many bubbles after drying. I did not wait long from the time I molded the bait until I applied the epoxy (1 hr). Should I let the bait sit for a certain period of time before sealing? It seems that it "off gasses" for a period of time. Is this correct?
Thanks
