It doesn't like nylon brushes
Thought i'd take some time and get some sealant on my wheels today, so took each one off individually washed, then sprayed with Iron-X and agitated with a brush and wondered what the smell of burning was !
It was the Iron-X eating away at the brush
Must say other than that it's the first time i've used it and it seems to work well.
