Guys,
Has anyone installed the Scotchguard paint protection film on their cars? I would like to know your opinion...

1. How good/bad is it?
2. Any pros or cons?
3. Is it visible to the naked eye?
4. Maintenance?
5. How does it reach to car wash, wax, polish, etc
6. Any issues in snow?
7. Contraction/expansion with reduction/increase in outdoor temperature?
