Nice 👌 What I don't get is h series says 150 2 hours for polymer and 2 hours 250 metal. Soo why can't you just spray all your polymer and metal same time and cure it all at 150 for 2 hours ?
The higher the heat, the stronger it will be. Polymer needs to stay around 180, so you get what you get. Set your oven at 180, spray your project. Let it air cure for 12-20 minutes, then pop all of it in the 180 oven for about 20 minutes. After that time, take your metal out, and leave the poly in for 2 hours. Once that time is up, take the poly out, run the oven to 250, and put the metal in for 2 hours.
