Some dumb guy in the past liked 5200 and used it everywhere. When we purchased the boat we needed to replace the windows. Wouldn't you believe it, the guy used 5200 to bed the Lexan. I had to chisel it out destroying the window frames along with the fiberglass recesses in the process.
Good news is that when I had to have new frames made I went with 2" stainless steel. A beautiful look but son of a bitch it cost me almost 5 grand for the frames not to mention 4 days to rebuild the fiberglass.
Why people use 5200 on things that may need to be replaced is beyond me. Same thing with your foam. If they had any kind of sense they'd have put a plastic buffer between the refrigerator and the foam. That looks like one hell of a job. Well done.
