I have orange peel like marks on my tail light after zainoing it (Z-2 & ZFX , Z6 after) .. any idea what it is... its not visible under strong sunlight...but easy to tell when you look real close in the garage... I tried rubbing it a bit but nothing came off, is it from inside the tail light? or is it supposed to be like that. (it's only found at the circles of the tail lights)

any idea what it is?

 

Not sure exactly what your trying to say. have any pics?
