I don't mean to hijack this thread in a different direction but it might be worth considering.......
I have a A4000T with similiar minor yellowing and I am thinking twice about retrobriting it.
1. I did the retrobrite process to my A4000D a little over a year ago and even though it is kept covered in a dark room when not being used, I have noticed a gradual yellowing coming back and it is not as white as when first done. There is info about this issue over at English Amiga Board and a possible fix by spraying a clear-coat on after the retrobrite process but I am concerned that this will alter the 'original look' by adding a different sheen or texture.
2. I have had a couple of bad experiences with retrobrite on A1200 cases. If I didn't get the whole procedure and time exactly right I noticed blotchiness and 'blooming' which was noticeable. If the same disaster happened to my A4000T case I would be beside myself with grief!
Opinions?..............
