I tried to buy or trial it to fit an alumite masking, but ... I was "impossible" as a result. I have not yet tried whether it is compatible with galvanizing or the like, but it is not alkaline resistant. I conclude that it is used for other purposes. There is "Chemically resistant" in the product content, but I think you should list chemicals that are not suitable if possible. Although it becomes a follow, it was able to stick firmly to the product which stickiness was outstanding and sandblasted.
