hmmm could be the heat. it would do to add a portable aircon or something to cool the room during hot days. As for me I bloick the sun out completely in my collection room. Though, Im thinking of rearranging so I can at least open a window when Im in it, so it doesnt feel so stuffy in the room. So far havent encountered any yellowing from the newer stuff , aside from the old ones which have yellowed before back in Phils. I have treated it with the H2O2 bath but alas theyve slowly come back yellowish now - e.g. AM Megatron. and I cant re dip them again coz the non white parts are already fading from the first soak.
Its kinda weird that encore skylynx would yellow, since it's quite new and away from light you say. guess they havent changed the formula for the plastic then...
