It sounds like you need to get her more involved in house work. If my wife wants something done, I'll usually do it but make her help, even if that means it takes me twice as long. If found she makes much less superfluous requests when she's going to have some sweat equity in it also.
Other angles, I just brush it on with an acid brush. Many people like them, other people like putting glue in used mustard bottles... I just like the normal bottle. Maybe I'll figure out a use for them, and I'll put mine back into service.
The wipe-off is the tricky part -- that's what Eric's alluding to... You CAN apply a super thin coat and just let it absorb/dry... But you've got to have your game brush on... It's a high-risk, high-reward strategy... I've executed maybe twenty to thirty pieces with ARS and I'm just able to pull that off rather consistently... But I still keep the clean rag handy... The key is even thin wet, no streaks, no dry spots... And practice, practice, practice..
