I'm not super familiar with paint strippers, but the ones I've used just loosened up the paint so still needed to be scrapped or scrubbed off. Having the rough surface may make this less than ideal.
Spec strip is what we called it, not sure what the full name is.
Was horrible stuff to use, the fumes put off were horrific and the tiny bit on your skin would burn like crazy. Worked well as a paint stripper though.
