I'll give you that the OP's specific application is far from a pristine platform from all appearances, but some reading and contributing to the thread might be concerned about such things. OP isn't the only one here. e.g. my similar need is on a minty example, and finding "do not use on painted surfaces" warnings on both recommended solutions does, in fact, catch my attention.
