I've seen a lot of Fort Maxes that have really bad discolouring not only on their white parts, but on their grey parts as well. I see a lot more yellowed Fort Maxes than any other G1 Transformer actually. Makes me wonder if he was made from a cheaper plastic than the previous years TFs? Did they start using cheaper plastic by that year or did they use extra cheap plastic to make up for the size of him? I don't see as many discoloured regular sized Headmasters, just Fort Max, so maybe they cheaped out on only him? So is it possible that the "Holy Grail" is made of crap? Or maybe he just got left in the sun more than any other TF ever made.
