Do you wipe off the swarf when you spray the stone then respray ? That will help. My 5K never glazes.
As far as a budget flattener , the Edge Pro glass is the least expensive but the set up then the mess it creates means you won't use it as often as you should.
I went with the 75mm X 210mm Atoma 140 grit. http://www.chefknivestogo.com/at14dipl.html
Yes it's probably more $$$ than you want to spend but it's really quick and easy - I bring it to the EP whenever I sharpen - and you'll be good for life.
