The clear coat on the left in the picture has turned amber and if you apply that over white it will cast an amber tint to any white or light color. The bottle on the right is okay,but if applied to white it will eventually do the same thing.It will yellow. I'd avoid both(over any light color) and use Testor's 1261 Lacquer clear spray that is formulated safe for enamels if that is all that is available to you. BTW,you didn't mention what TYPE of paint the white panels,or the rest of the model will be painted with.
