I test about 20 different glues on foam. I got a few surprises. Check out my video.
It rained lightly during the entire glue drying period, making this more of a torture test. I was disappointed with the results from more than one glue. Yeah, I also had a very unexpected spectacular failure.
The video is about 50 minutes long. Sorry about the length. There were just a lot of glues that I wanted to test. I talk about gluing foam in general, not just about the test results.
To see my recommendations, you can just watch the last five minutes. I also summarized my recommendations in a follow-up article.
