i did this to the supra a few weeks ago and to the tiburon. i just took a spraying bottle (an empty Fantastic one actually), filled it up with dishwasher soap and plenty of water, and just kept it heavily wet while scraping it off.
i only had to scrape for around 5 minutes before everything was wet enough and i had taken a piece big enough that i could grab with my hands and pull the whole thing off in one shot.
if i get a webcam, ill even do a small picture tutorial with the windshield (only tint that i have left).
Supra: To surpass or go beyond.
