A spray that can make any object practically indestructible: this is the most synthetic definition of Line-X. By covering a watermelon with the spray, it is possible to prevent it from breaking even after a throw from over 50 meters high.
Line-X coatings have been in existence for some years now (mostly used to protect truck bodies), but their fame has only recently arrived after many have started creating videos in which they put the products covered with spray. Line-X has been tested on watermelons, eggs and light bulbs, with incredible results.
Line-X behaves like a powerful bi-component glue: in fact, the spray is composed of two basic substances that once joined together create the super-resistant coating. The’ secret’ of the product is that the two substances are mixed when spraying, as the solidification process takes place very quickly and therefore the substance would be impossible to apply if they were mixed earlier.
The authors of the “How Ridiculous” program launched a watermelon covered by Line-X from a 45-meter tower: the watermelon bounced like a ball without breaking. Not even an Axe was enough to break it, but they had to use a circular saw.
In Mythbusters, Line-X has been used to protect a man (or rather, his jacket) from the repeated bites of an attack dog, also to protect concrete and wood blocks from a controlled explosion of C4. The only test that failed was a simulated car crash, where at high speed the spray-coated car suffered damage similar to that which had not been sprayed with the product. However, the coating was effective in protecting the car from low-speed collisions.
