Looks really nice!! Keep the pics comming..
i don't know about the rest of you but i let the paint completly dry for at least a few hours. Then i used an old soft toothbrush and gently scrubbed the mustard off under a tap of luke (spelling?? finger warm if you know what i mean..) warm water. Then i used papertowel (the good quality stuff, the one that doesn't leave lint) to wipe any remains of water and mustard off...
and concerning the mustard smell.. i found that most of it.. if not all disapers after you put on a layer or two of clear lacker.
