Sean,
GREAT video! I tried that 'Icing' stuff before, but I found it gummy. I think I see why.... compared to you, I used WAY too much catalyst. With the proper amount of catalyst, how do you find it sands?
If you're using a bar sander, how do you keep the end of it from digging into your wing skin? Are you doing all of this post-glassing? Thanks for doing the video, and thanks in advance for your answers.
