I think I have good news on the Mirage F1 decal front! I tried a new batch of liquid decal film on my old oob Airfix decals. I applied the stuff, let it sit for a week, then tried one of the tails badges last night. It still took forever to soak off the backing paper, but I was able to float it into place on the model, pressed it down fine with my trusty lint-free cloth and.... no curing/flaking this time. So, if all goes as planned, I should have the remaining decals on this evening, sealed up tomorrow, undercarriage & weathering taken care of by the end of the week!
