I had bonded the two half’s after I trimmed them without pulling them from the molds. This time I pulled the parts. Cleaned and sprayed new pva on the mold and the outer surface of the plug. So....this time although it will still spooge out it shouldnt want to stick to anything. I’m going to foam it while it’s still bolted up after the bond is cured. I foamed my practice fuse and I gained some precious knowledge. I built a hot box too, I really want to get maximum thermal,expansion out of this foam. I was really surprised at the pressure the foam can generate. I have 3 holes in the mold to pour into and I blocked 2 with my thumb when they started to overflow and apparently the top hole expanded and sealed. I moved my finger and got just sprayed with foam lol. Was fun. If this flies well I will be remaking my molds. First mold I’ve ever made and I could have done better
