A strictly positive distribution $D_{sp}$ has values $D_{sp}(x)&gt;0$ for all $x$. This is different from a non-negative distribution $D_{nn}$ where $D_{nn}(x) \geq 0$.

What is a "strictly positive distribution"?
I've got a faucet in my bathroom that has a bit of the finish peeling off after what appears to be some kind of oxidation has built up underneath it. I'd like some suggestions as to how to repair this - the faucet is in otherwise good condition.

Should I try a paint? Some kind of touch-up pen? Also, I suspect I should remove the bit that's peeling and try to remove the powdery, white oxidation prior to any repairs, yes?
