Yellow plastics are easy to turn white with hydrogen peroxide and uv light but stopping the plastic from yellowing again is my problem. My question is this: after getting your plastic item back to its correct shade of white would applying automotive clear coat prevent the process reversing iteslf? I can clear coat in gloss to matt and everything inbetween and as its for cars i would assume uv stabilisation is a feature of the process. Could this work?

Yes – the clear coat you add must contain UV stabilizers. If it does, then in principle, you can inhibit the yellowing
