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?..............
Yeah the blotching occurs if you dont put even layers of a very light coat... you cant just slap the stuff on (not saying you did haha) My advice is to get a brush from a beuty supply shop they use for applying tint or color.. and use that

Nice amiga. Great to see a 4000T with the faceplate intact. Those A/V modules are hard to come by..good luck
