Winter's a coming.

Winter's a coming and I want to keep the rust away from my truck which I wash and wax often. What would be the best products to use to stop the road salt from deteriorating my truck?

For the stuff you cant really see I blast it with fluid film.

I'd take a look at Waxoyl. My winter car was treated many years ago and still holding strong.

Regardless of what type of treatment is done/not done to the underside of the vehicle, I feel an important step in rust prevention is keeping the salt from sitting on any surface for a long time.

In the dead of winter, I'll hit a touchless car wash that has an underbody spray option and then roll REALLY slow over that step. If that's not available, I've also simply used the spray wand at a coin-op car wash and thoroughly sprayed off the entire underbody.

I like 3m rustproofing spray for body panels and a thin coat of undercoating for the undercarriage. It's a good idea to touch-up the undercoating every fall.
