Yellowed Decals Question

How will the yellowed decals turn out on the model when applied?
And is there anyway to "save" it?

Take the decal sheet and tape it to a window that gets plenty of sun and let it there fore 3-4 days and it will get the yellow out. If it is yellow on the sheet it will be that way on the model. Especially bad on a white model. The sun treatment works,try it you'll like it.

Thanks! Tape in front or behind the window?

Tape it against the the window with the decals facing outside so they get the sun.

Thanks again, I will try it~
