Is there a guide (ideally with pictures) of how to do RetroBright and apply it? I have been trying to do it for some time now but never had any success. I even bought an extra A500 Case to test on! On some sites there are instructions of how to build RetroBright but on another forum I was told to just use BBlond. I really would like my A500 to look like new again but cannot seem to get it to work!
