I always had better results (due my particular working style and/or materials?) with weak sensitizers; I use only two dichromate strenghts 5% and 2%. (AD, 1+1 gum/pigment+dichromate.) I also have 10% on hands for unusual situations though.
Which dichromate is that, Loris -- potassium or ammonium ?????? J.
