what do you mean by this? fluidlines and paints are technically for different uses. fluidlines are specifically marketed as a gel/liquid eyeliner, whereas paints are marketed as shadows/shadow bases. both, however, can be used as a base. generally, though, for a base, neither is as good as shadesticks and urban decay primer potion are. paints and fluidlines both tend to crease, and most of the paints don't enhance color as much, because they aren't as vibrant to begin with (with a few exceptions..)
