I have been following the discussion sense posting it. There does not seem to be a residue from the treatment and color enhancement is notable. For me, it is the silver bullet to bring to life a few of my oldest signs that were in need of help. My Supreme Oil Sign lettering at the bottom was really faded. I wonder if the cobalt blue has a stronger reaction to treatment. I am not the expert, but I sure am pleased. Also, I sure understand the discussion about not wanting to deceive anyone at sale but for the “bringing back to life” of my 1920s signs I keep in my personal collection...this is great!
