In the same vane (AMHIK), I've found that a wetting down with CA accelerant like zip kicker, will easily remove enamel.
I had some clear canopy for a F4B/N 1/48 scale Phantom, that I applied liquid mask and had a small area that was not covered. Removing the mask after air brushing found that spot. I took a Q -tip very lightly soaked in Zip Kicker accelerant and lightly rubbed , removing the paint. Only a slight foggy residue remained. I soaked the canopy in Future floor wax, eliminated the fog. The clear plastic was not harmed.
