If you like the General Finishes Gel Varnish you wold most likely "love" any other brand.
I have used Barteys, Lawrence McFadden, General Finishes, Old Masters, and Verithane gel varnishes.
I absolutely hated General Finishes "Gel" varnish and I tried it a couple of times. I do like and have been using their other products for a very long time.
What I don't like about the GF Gel is that it has a consistency/thickness of apple sauce, not really a gel.
All of the other brands that I have used are more like pudding and or Vaseline and I feel they go on more consistently and cover better. They will not run or drip like theGF Gel that I have used.
