Since I have my car apart, I have a lot of the parts in the attic. I went in the attic today to take an inventory of what all I had and I instantly felt the extreme heat. I have been storing my driver quality headlight bezels along with my excellent condition taillight bezels and grille in the attic since about January. I figured it would be a good place to store them since it was out of the way of everyone, dark, dry, and critter-free. Today when I felt the extreme heat in the attic I took the bezels out for fear the heat would make them brittle, as they are 27+ year old plastic. I am wondering, does the heat affect the parts that much or is it more the UV rays that make them brittle? I want to protect these parts from any further deterioration as I paid a good deal of money for them because they are in nice shape and I was planning on putting them back on my Regal once it's painted. Plus I don't wanna pay $200 for a pair of new headlight bezels.
