A friend of mine uses cosmetic cotton pads(get them at your
local dollar store)? to apply Kodak Photoresist (KPR). When it
is dry he places the unexposed boards in an old phone book for
storage and pulls one out (all under a yellow safe light) when
he needs one. He has used this method for decades.
