I recently bought a Do It croaker mold and once I finished injecting it, I let it cool for 4 to 5 minutes.. BUT it came out way too soft and mushy. This is the same plastisol I used to pour senkos and they came out just fine. I am new to it all so any help would be appreciated.
I know there is hardener additive out there but I am just wondering why one mold poured and cooled fine and the other was too soft and stayed that way.
