Action Figure yellowing explained: Causes and how to hopefully fix the dreaded yellow plastic syndrome
Welcome to my first video of 2026! This is the kind of new content you can expect from Hunter Knight Customs!
Yellowing plastic used to be something collectors expected after YEARS… so why are figures from 2020 already showing signs of photo degradation?
In this video, I break down the science behind the dreaded “Yellow Plastic Syndrome” that’s been affecting modern Transformers figures — using Earthrise Megatron as a real-world example.
But I'm not stopping at just diagnosis.
I’ll show how customization can save a figure that’s already been hit by photo degradation — including paint matching, coverage techniques, and how I gave this Megatron a full glow-up with a few added factory-missing details.
If you’re a collector, customizer, or just tired of seeing your figures age like milk in a sauna, this one’s for you. Watch the video ON YOUTUBE or click below:
