You would have to be SUPER careful with this trick. MEK runs as easily as alcohol and if a drip runs across the face of the plastic, you'll have a streak that is an absolute bear to get out. Or worse.
I've seen a guy spend all day getting a new windshield into a small airplane and then totally ruin the windshield while using MEK to clean some sealant from the edge. A single dribble ran down the new plastic. ???
