Actually, no. In the rest of "Against Method" it's pretty obvious that Feyerabend is saying is that since even our methodologies and standards of evidence are paradigm-dependent, none of them really allow us to objectively connect with reality. As a result, epistemology and science are "anything goes"; any standard of evidence is acceptable no matter what it is. So he's closer to a relativist than a rationalist.
