Some countries spend billions on the development of something and we just use our pensioners :mrgreen:
Not sure if this is true or if it works but I would not be surprised if the German engineers did it. The German technology has always been top notch.
Radar Absorbing Material is nothing new - it’s been in widespread military use for nearly 40 years now, and many forms of it come as paint. Nothing in this article even suggests he has a particularly good paint either.
Radar absorbing material has already been in military use during ww2 in germany.
How you read the article that you think it doesn’t “suggest a particularly good paint” remains your secret, however.
Spiegel would hardly mention the stuff, if that wasn’t the case, neither would I bother posting the article if the article wouldn’t suggest precisely that.
Looks good, if you have more links about it bring it on. 
Read it carefully. To me it reads as a “human interest - old guy in shed beats boffins” story, rather than a technology one. Then read the “astonishing” bits - with a single exception, they’re all astonished that he cooked it up in a shed, rather than how much better it is than existing paint. Finally, look at the type of people who want to buy it - they aren’t exactly those with access to advanced RAM. I would suggest that this implies the paint isn’t particularly good.
