No reads on villain, not sat down long.

I considered raising on the flop to $6ish, but I thought that just folds unpaired overcards and gives away money to higher pairs (and I think those two together make up most of an unknown's range as an UTG raiser.)
I can't see folding to his turn or river bets given their size, but should I raise on either of those streets after just calling on the flop?
