The call is fine preflop,considering that BU called as well but I think a raise can still be considered in this spot.
On the flop you should check/raise because CO kind of looks like a TAG and he will often make a cbet here.
I'd still protect even a bit bigger ~$0,46 and donking into multiway pot is totally fine. You wont get much action anyways if they don't have a hand. Nice hand!
