If you want proof that the hood is aluminum. Take a magnet off your fridge and place it on the hood. It won't stick because it's aluminum. As far as rust proofing. I wouldn't recommend it. The hood and tailgate are aluminum and everything else is double sided galvanized steel which after the body has been welded together is submerged in a rust inhibitor primer which has electrical waves going thru the tank for addition adhesion. Then the body is painted and cleared coated. As long as you don't have a bare metal scratch you should be good for at least 10+ years.cfedor said:There have been reports of bubbling paint on the front corner edges of hoods. BUT, the hood is aluminum - so I have heard. Anyways, yeah, I agree don't waste your money and use the money for other repairs or accessories.
Ha! Grimm pre-referenced as in for sometime in the future, an Enclave becoming a "Classic"! That's classic in and of itself!Grimm said:It's been debated that if you live in a snowy area, that you should leave your car outside in the winter. It is said that the salt will start to eat away at the metal once it gets in warmer temps inside a garage, where if it stays outside it will be too cold to do this. Also, periodic cleaning underneath during the winter would also be important. But unless you plan on keeping the car as a long term classic car, I wouldn't worry about it. If you keep it clean regularly, you shouldn't see any significant rust within 10 years. If you do, it will be because of a design flaw most likely such as the gas fill of my car because they put a drain hole inside. So the rain/dirt from the tires goes up through that hole and sits in there causing it to rust over time. And anything you do short of making physical changes won't help prevent it.
:thumb: Agree this is best. Our 2008 is kept washed year round, never been bent, and any scratches are treated immediately. I must say, though, that after almost 7 years, the underbody doesn't look quite this good still. :happy:Grimm said:
