bathtub spray? any info?

[Guest guest]

Does anyone have any info on a kind of spray they use to refinish bath tubs? My

husband wants to ask them to do this in our new apartment in one of the tubs,

but I am wondering if this stuff is toxic. They did it in this apartment two

years ago when we moved in.

I don't know what it is, but it's some type of white spray that kind of

refinishes the tub.

Thanks
