HI
paulson games,
I have been watching your thread grow for some time now. That is a really nice, sharp, and clean paint job! I have a Hasegawa 1/72 Valkyrie stashed away in my growing collection of 1/72 kits... you've resurrected my interest in building it.

The problem is due to age of the model kits the majority of them have yellowed up pretty bad and I don't think they will be useable.
You could try leaving them in the sun, no harm there if you think they might be spoiled by age. While I haven't tried it myself (though I have a tons of old yellowed esci decals lying around), I've read numerous reviews/builds of scale kits where the author has resorted to this technique to bleach the age out of decals sheets successfully.
If I get around to trying it (not easy this time of year in southern Canada) i'll definitely pass along the results.
