I'm kind of re-taking an old hobby of building model aircraft. I finished my 787 Dreamliner (Zvezda) and found out that it was a painstaking job to remove the paint from the transparent windows after painting all the aircraft with enamel. I used an exacto knife to scratch all the windows and it took a lot of time. Now I'm building a 747-8 and, as you can imagine, that's double the work with the amount of windows that it has (I have an A380 queuing after it, too). So here's the question: is there a more efficient/easier way of removing the paint from the windows?
Thanks a lot in advance!
