Clay compounds are a bit strange. They aren't as soft as something like a super soft compound, but aren't the same as a soft compound. They work really well on clay!
I don't believe AKA has a clay compound. PL is MC, JC is Gold, Panther is Clay, Losi is Pink. If you're running on a tacky clay track, there's no substitution for a good clay compound and some traction additive.
