A few comments on process so far.
1. You know that thing when you pull a thread on a sweater, and before you know it you have a pile of yarn and a huge hole in the sweater. That happens with dope too.
2. Clearly my approach has changed from fixing small spots and rejuvenating to stripping the compromised areas. After seeing what the fabric looks like underneath, and how poorly the dope adheres once broken, I think that will work out better. I will still spray a coat of rejuvenator, but the intent will be to stabilize the areas where the finish is still good.
3. I tried several stripping methods, but the one that works best is a moderately sharpened paint scraper. Once you learn the technique for getting under the film sheet, you can strip large areas very quickly. You have to be careful not to go too far, unless you want to repaint the whole thing. I probably could have stripped the entire left side of the fuselage in another hour. The hardest part is the areas directly on the longerons. I had to use thinner there, which takes a while and makes a mess.
