hmmm my G1 downshift is starting to yellow as well - kinda like Classics Ramjet, and my collection room is blocked out from the sun... prolly those plastics used really do just get yellowed after some time (plastic formula problem) better grab me some H2O2 again...darn now Ill have to buy another sticker set coz it will peel off.

Also the ones I did soak and gotten white before - AM Megatron, RiD Prowl did yellow again after a few months but I dont want to dip AM megs again coz the other colored bits of him are already fading (purple groin, eyes, fists)
