Fold, you'll have a hard time showing a profit vs a range of sets draws and a few bluffs OOP here. Remember draws have shitloads of equity vs you on this board and you're not going to be able to play turns well without a better idea of his range and frequencies.

If you're worried about being exploited in this spot then just call with all the way better bluff catchers like QQ+ with a spade. In fact since he seems to like to felt meh draws on wet boards I'd probably just be 3 bet/calling the flop with a stronger range, namely stuff that has more equity vs said draws. Red 99 = easy foldage. AsJs = easy 3 bet/call though vs this guy.
