I want to sun bleach spider-man

​ I made a reddit for this, im sure many marvel fans have plenty of spider-man mini figs i personally have around 30 of the generically common one so im hoping not to hear alot of "dont ruin the legos" there's a picture here just for you. But genuinely I just need to know if there would be any real change, I see clones turn yellow but thats about out. Secondly how long does it take. And lastly this does make the mini fig more brittle id assume? Thank you fellow nerds any insite is major:) ...
