The past two days I covered the flap and ailerons that I have been building. I started with the flap first and royally screwed it up the first go around. Once I watched my covering videos from Stewarts System again I was able to cover both control surfaces with no problem. The Stewarts System glue was extremely easy to use and I did everything in my kitchen. I've never used the other covering methods but after hearing all the horror stories from others I'm hooked on the Stewarts System. No fumes, no mess, don't have to worry about glue drying on you and a quick water clean up!
