masking fluid disaster 2

I spent last weekend ruining my latest painting. I had a bad experience with a new type of masking fluid called "Molotow". The stuff comes in a pen and was super easy to apply and I was initially very pleased. You might be able to see the blue dots on the trees. They were supposed to eventually be highlights but the stupid stuff wont come off and now the painting is ruined with blue goo.
The packaging did warn not to leave it on for more than two days but I tried to remove it on the next day and it just smeared. I had a similar thing happen with regular masking fluid once before but in that instance I had left it on for over a week so that was my own fault. Last time I did eventually get the regular masking fluid off by putting the painting in the freezer, but this stuff seems to have partially soaked into the paper, I cant even scratch it off with the edge of my palate knife. I was really likening the colours on this piece too.
 Dam you Molotow.
