Sorry, I was feeling cranky last night. One of the things I like about making my own sauce is that I can avoid liquid smoke. Store bought sauces almost all have it and I'd rather taste the smoke I spent so much time putting on the meat in the WSM than the liquid smoke. On the other hand, to add some smoke flavor on something I didn't smoke can be a good thing.Ruin? The liquid smoke rounds out the flavor for me. To each his own, but I wouldn't want to ruin it for you.
EDIT: spelling error.
