End of the day it's only you who can decide & anyone who told you it would be ok for a little job would be wrong to do so in my opinion. Normally problems with stuff like this is due to long term exposure rather than a once in a while use but there is always a risk even for occasional users. Personally I would use a water based acrylic paint, finish might not be as good but it would be good enough for me. Pretty sure you could still get a finish you would really be proud of with a different type of paint if you used some of the finishing products/techniques that have been mentioned by Chris.
