[Coco] retrobright

[Gabriel Holland]

All the stuff I have read says that it is usually plastic that was brominated to help reduce flammability and the bromine is displaced by oxygen over time but it is accelerated by UV.  Hence, a clear coat over top to prevent oxygen from contacting the plastic surface.

 I'm pretty sure it's the chemical
 makeup of the plastic that causes the 
 yellowing -- yellows as it ages. Different batches yellow at
 different 
 rates. The best long term protective option might be a good
 paint. That 
 will protect the plastic from UV rays as well as exposure to
 other 
 chemicals, should make it last longer before it becomes
 brittle. Not 
 original, but what's the point of having it original if you
 can't handle 
 it for fear or breaking?
