Thanks! I think I will settle for what crackling I do have and do the vaseline technique for the rest of the bed frame.

sumusumu--that's a good question. I think applying it with a foam brush would work. I'm not a big fan of crackle finishing in general because of  getting that second coat of latex on at just the right time. Do you have your heart set on crackle for the bed frame? If you're looking for an distressed/shabby chic look, have you considered the Vasline trick? That would give the metal dimension and would be A LOT easier than the crackle route. Here's a how-to I did awhile back distressing a picture frame. The same steps can be applied to any paintable surface. And instead of  Vaseline, you can use a candle. Just rub the edge of the candle on the edges of the bed frame where it would get naturally worn.

That's great!! I can't wait to see pictures!!
