Foam board oven . I have the sides just taped up with masking tape so I could remove it for storage. It worked fine but you have to watch it and re seal it if it starts to loosen from air pressure. I ended up cutting a hole at each end at the bottom for air flow. The heat gun works but it could be a little hotter. It’s only pushed in a little so you don’t overheat the plastic on the heat gun. I got up to a higher temp on the next video.
