However applying retrobrighting on a 28’s keys is only for the very brave, simply because taking the calc apart is hard and putting it together in good cosmetic condition is next to impossible…

yeah taking it part is out of the question. There's a hair dying product that contains the hydrogen peroxide used in retrobrighting and it comes in gel and cream forms. I think i will look into the gel stuff to find out if i could apply it directly onto the keys and then have it somehow removed without risking any of the stuff getting into the calculator through the gaps around the keys.

but yeah it's not a big deal, if it's not 100% safe then i won't do it.
