  I quit using Sigma coat a couple of years ago due to its unreliability.
  I now use Gel Slick from AT Biochem and it works much, much better.
  Just clean the plates once with 2N NaOH and then with soap and water. 
  Apply Gel Slick, wipe off and you are done.  Only need to reapply the
  Gel Slick about once overy 4-5 times you use the plate. It works perfectly
  every time.  No I do not work for AT Biochem or know anyone who does.
