I'll have the same results if I try to move the N number like you did. I'm actually going to paint over the old numbers in white and then mask them off when the top half of the fuselage is painted red so the numbers will be white. They might get a blue outline when it's done, don't know for sure.
Now that I have a more definite plan on the new trim scheme, there is less sanding to do and things are moving more quickly. One side is done, we'll cut the grass and edge a few trees today and then get back at it.
Learning to really savor the small victories helps keep things moving even when they're barely moving so, in the name of small victories, I present "Loose Headliner Tab Reattachment". I am just happy I caught it and fixed it before everything else was back together.
All of the stripes and N numbers have been sanded enough to paint over them so it was dragged back out of the garage a couple of weeks ago and washed/degreased again in preparation for final scuff sanding.
A 3" tape was also put over the existing 2" tape on the belly where there were signs of stress. It was also cleaned really well and then sanded down to the silver coat before the new tape was glued on.
Right side is just about done, now for the bottom. Today's little victory is having figured out how to mask off an open door! I woke up today like, how the f' and I going to close off an open door? Voila! Lots of masking tape and some paper!
Removed the left wheel this morning and found a gunked up, lousy looking brake mounting plate along with an axle that looked worse than homeless. who wants to guess what went down next?
Disassembly! Brake plates got cleaned up and painted, axles got cleaned up and painted, stubs of the gear legs got cleaned, sanded, and primed so it can all be bolted back together tomorrow, masked, and ready for prime/paint.
