The Big Box stores, at least in my area, no longer carry either in anything less than gallon cans. Not too long ago I could get it from them in quart cans.

Just another reason why I support my local hardware store, even though I may pay a few pennies more!
Oops. My mistake.....I misread the post.
Quarts of xylene (xylol) and toluene (toluol) can be found at most paint places and small hardware stores. Here's a quart of toluene at ACE:

You might experiment with acetone.....but it's a different animal than xylene or toluene.
