Carl doesn't look like himself in this video, wearing that hat. David Marks wears shades a lot, too, so maybe their fondness for shades is a Beach Boys lead guitarist thing.

Stamos' intention was to make the "Croc Rock" video look as cheesy as possible in a "camp" (deliberately tongue-in-cheek) manner. In that regard, I don't think he quite achieved the "camp" element.
Well, if a key component to something being camp is for the audience to be aware that it's camp...no, I think he didn't. That's a tricky balancing act, though, even with people who have experience directing camp successfully.
