Query: Easy on, difficult off

After reading all the reviews, I had to try it. Well, it went on easy enough and cleaned up smudges in the paint that didn't come out in the wash. BUT... never set up well. It gummed up my terry cloth buffer to the point I had to throw it away. Used up 4 more buffers before I got it all off. The car finally had a nice shine when I got all the gummy residue off. We'll see how long it lasts... But I won't be using it again.
