New paint for stealth jets is even better at hiding them from radar and lasts longer than the coating currently used on USAF's fleet
The spray-on ceramic allows engineers to quickly apply the stealthy skin without sacrificing designs that hurt the jet's speed and performance
The skin is 'harder than sand' when it sets and withstands harsh conditions
It is applied as a liquid and becomes hard when exposed to ambient air
The new coating can also withstand temperatures over 3,000F
