I need a bit of help here.

I put the 3M plastic protection film (ClearBra) on my headlights on my '00 RX300 when purchased new in '99. Over the years this plastic has gotten very yellowed and brittle.

Recently, I stuck my fingernail under the edge and, basically, just pulled the old brittle plastic off. Now I'm stuck with a layer of glue that is pretty hard.

Anyone have any experience or recommendations as to how to remove this old, hardened glue?

 

goo gone... citrus based sticker remover.... works wonders, won't damage the light...
