I continue to advise against using dichromated mixtures with foam rollers.
 
How did you assess the validity of your tests ? Why did you use water rather
than the gum mixture which would have been more appropriate ? Did you try it
under differing humidity conditions. How did you measure the micro droplets
? Did you conduct your tests wearing a mask ? How did you test for the
filtration effects of the mask ? How would you test for the long term effects of
micro droplets of a corrosive liquid on the lungs ?
 
If it happens with paint......
