oh im not sure. i know i tried to order some more a little while ago and they told me that they couldnt sell me any just because they have had some fire problems in one of their factories and they lost a lot of material. mine looks great with no sanding thou. granted im sure it would look more stock if sanded. but most people cant tell that it was rattle canned. everyone thinks that i bought aftermarket lights for it when they see it. im not sure about the removal of the product either because i havent had any need to remove it myself. i was just throwing in my 2 cents about the best product to tint lights in my opinion. ive used it on my car and my friends have too and they are all happy with it.
