YOU'RE YELLOW! VF-25F turning all sorts of colors

[MKT]

My YF-25 and Yf-30 have also majorly yellowed like @enphily's pic above. But that was own fault as well as didn't properly keep it away from sunlight in early days of collecting.

Speaking of which, Bandai needs to reissue the YF-30. Kinda strange they didn't milk the mold for this.

I was browsing BBTS and i came across this:

Anyone have experience with this product? Does it prevent yellowing?

What would really be great is, if someone would invent something that permanently restores yellowed plastic.

A bath in a hydrogen peroxide mix and exposure to a UV light will do it. I did this to restore an old, white Kenner TIE fighter. You’ll have to do some disassembly and need to expect any stickers to degrade.

Peroxide bleaching is unfortunately not permanent. In my experience they will go back yellowing after about 1-2 months, tried on a Yamato VF-1, Yamato VF-22S, DX YF-30, DX VF-25, all turned yellow again. It does help on severe sun damage though, at least it only goes back to slightly yellow not sunburnt dark orange. Also please do not use UV light, what peroxide bleaching actually needs is the HEAT, not the UV light. We already have cases of UV burns and partial blindness because of unsafe retrobrighting setups that use UV lights.

I wonder if sealing it with a UV blocking topcoat will help it from returning back to yellow 🤔

I have an old PS1 that I used the above technique and it hasn’t re-yellowed. Begs the question how much it’s tied to the chemistry of the plastic.

I’m curious if that product from BBTS would help prevent yellowing after re-whitening the plastic. The only issue with any top coat is it’s likely not easily removable to re-whiten if it doesn’t work.

Tried this. Answer is no.
