So I taped the decals to the window as
@mach7 suggested many moons ago, but unfortunately the yellowing didn’t come out. I think it’s because the yellowing was probably caused by water stains rather than normal yellowing of old decals. Also, one of the Martin Marietta decals ripped at some point (before I got around to applying liquid decal film). So, I ordered some new decals, but I want to try using as much of the old ones as I can.
I first got the Semroc decals, but they are not exactly the same. I knew that some were different, but I was hoping the Martin Marietta ones would be the same. Unfortunately, they’re not. If you can’t read it, it says Semroc Astronautics.
So, I have a set of the Tango Papa decals on the way. I already confirmed the blue decals say Martin Marietta.
In the meantime, I’m trying to apply as many of the old decals as possible. And it’s turning out more difficult than I thought it would be. The decals do not want to release from the paper. I’ve managed to get the 4 black two-dot decals in place because they are very small and were able to release with some coaxing.
When I tried a bigger decal, I ended up tearing it even though it was in water for over two minutes (with me checking it every so often). I’m going to try one of the stained decals next to see how long it will take to release from the paper. If anyone has any suggestions on how to get the decals to release more easily, I’m all ears. If I can’t get them to release, I’ll use Tango Papa’s. But as I’ve said before, I’d really like to build this kit with as many of the original parts as possible.
