I'd only re-apply it if it looks like it's drying out. When I did the tests on the C64 that is pictured on the Wiki, I removed the gel every two hours but that was just for photographic purposes.
Retr0bright is good for at least 48 hours with the mixture you have made up. Out of interest, how much Oxy did you add to it, or did you use the TAED I sent you?

Now then, where were we.
Okay, this morning - didnt have time to examine them properly as I was on my way out for the day, but upon returning, we are having some positive results. The B key is whitening, you can still see the line between the lower white colour and the upper yellow colour, but it is getting there. The 1200 case has brightened very well so far. The external floppy drive is still quite yellow, but to be fair it was the worst affected of all of them. So all three B key comparison pics.
So looking good so far.

Again this morning, very little change from last night, but sunlight seems to make all the difference - it whitens much more quickley during the day. Only by examining the key closely can you see the two tone colours. The disk drive is still some way off being done.

I found exactly the same: sunlight is the key. I have a UV lamp, but that seemed to do little...
Yup, they certainly load up the Oxy with UV brighteners, don't they?
I went to college with a guy that worked for Ciba-Geigy when they were at Clayton; they made these UV brighteners (or up-converters, to give them the proper name).
His lab coat glowed so much in sunlight, we reckoned he was getting skin cancer from it!!
:rofl3

The case is nearly done. The picture was taken during the day, which makes it seem brighter than it really is, the original shot was taken in the evening - so it does look good, but in reality isn't as bright as it seems on the picture.
The main reason it took me so long to get started was due to the fact I could just get cream peroxide - I thought that this would attack the plastic. But, the concurrent retr0bright thread on EAB recently mentioned this was fine. So I have another batch of bits using that and a small sprinkle of oxy. This time they are in the garden, I'm not sure how much the UV bulb actually did. As I said earlier, all the brightening seemed to take place during the day.

Yeah,
I think it's the wavelength of the UV that's the issue. We need 320nm UV light and most black lights are weak at this wavelength, unless you pay an arm and a leg.
Good results though!!

Thats a pretty self evidential statement Zetr0 - everone knows that!
If you have a lump on the side of your head.
That's why we all love him to bits.
Good job we all have different kinds of lump eh.

We spent enough time researching it! The threads are all over EAB. VCF and lots of other forums.
Aye, we have definate results. The cream peroxide mixture seems slower, which is a shame as its a lot easier to put together and much more pleasant to work with. Stil, patience is a virtue ..............
