I'm pretty self sufficient with my molds, but had to buy an Arp blank. I had some alterations and sculpting to do, so I put my epoxy work in the sun to help cure it (I do this all the time with my blanks). It's only 60 degrees here, and the whole side of the fish buckled severely! I cut an observation hole in the back of the fish to try and determine the problem. It was obvious that very thin spots in the plastic from roto casting, also very inconstant thickness in both the plastic and the foam. Very unstable situation. Now I have a lot of time in the fish and it's crap...........Anyone ever had this problem? I have a call in to Phil Helms to discuss.
