We were told to apply fibered aluminum roof coating to our roof because of a leak. We did. Now, how long does it last before it needs re-coating?
try out michelin x-ice xi2 i tried michelin x-ice 1 and they were really impressive! i could only imagine x-ice xi2 to be much better because its a later tire. i remember once my dad was in his corolla with four x-ice's and was testing them out. his car doesn't have abs btw. we were traveling at 30 km/h and he hit the brakes hard, and they didn't lock up!!! and we had a rwd van with x-ice tires at the back and we never had problems! terrific tire, get the michelin x-ice xi2. bridgestone blizzaks are good too, both the x-ice xi2 and the blizzak have special rubber compounds that make them superior to your average winter tires. but once the blizzak is 55% worn, the special compound will be gone and it will behave like an ordinary winter tire. the x-ice is designed to have the same rubber no matter how worn out it is.
If they were perfect mirrors, yes. But nothing reflects perfectly, and the energy would rapidly dissipate in a fraction of a second (during which thousands of reflections would take place).
