Spotting is no big deal to me. I use Spotone and, mostly, warmtone papers with some Ilford MG IV neutral tone. I usually tone in Kodak Rapid Selenium Toner, Nelson Gold Toner or Kodak Brown Toner. I have a plastic "I Can't Believe It's Not Butter" canister top that has been splashed with Brown, Sepia and #3. Although it dries out, it can be reused until nothing is left. I use it following every print session and I can mix the colors to match virtually perfectly. I give a #000 sable brush a lick with my tongue and dip it into the solidified mixture, wipe the brush to remove the excess and go to work.
The trick is to start light and work darker and to use the smallest amout of Spotone possible.
By the way, a bottle of Spotone lasts for years. I used my first Spotone #3 bottle for 20 years before it needed to be replaced. I splashed my current mixture on the canister top over four years ago and I'm still using it. It's no wonder the company recently went out of business.
