I picked up another leader ROTF Optimus prime a while ago and realized its quite different to all the others, it seems to have a yellow tinge in some areas of plastic including the front windows chest collar pieces, vehicle front grill, gas tanks and some other places
At first I thought it was a custom or just dirty, but did not smell of anything or paint, so I tried washing it up but it was still there
Not sure at all what it might be, not dirt, not stains, custom? Rare edition?
Please tell me what you think in the comments below

Sorry not sure how to upload the pictures I took

 

KO?

 

Was it already opened when you bought it? The figure came out in 2009 so that's plenty of time for it to become discolored from sunlight and it wouldn't smell or otherwise appear dirty.

 

yeah sounds like sunlight staining, I've had that happen to a few models in the past. It will stain the plastic yellowish.

 

Oh that explains it, yeah I got it used without packaging, must be sunlight staining, don't know where the previous owner left it
Thanks guys,
Well I don't know what to do with now, is it worth keeping? Already got the couple originals, hftd battle damaged, buster, striker and dark of the moon prime

 

You could always use it for spare parts, or be creative and make a custom.

 

Yeah I've done A couple on prime, still working on them, seriously you have no idea how many spare/ damaged ROTF primes I've got (9)
I've just finished my ROTF megatron custom, just going to post it now in radicon customs check it out
