My owners manual says to examine and reapply undersealant. It says to do this before and after winter. I deal with a very salty winter here. What products are available to do this? Do I have to reach under the vehicle ar just the wheel wells? I hava 2011 g37x.

 

interesting, id like to know as well

 

The section in the owners manual regarding this is 7.3, "Appearance and Care".

 

Are there any snowy weather drivers here that deal with very salty road conditions? What do you do to protect your car in these conditions?

 

For the wheel wells and under neath parts I'd suggest spraying the Chemical Guys Bare Bones Undercarriage Spray on them. It helps clean and protect in one step so you get great results. Check out this article on the topic - Product Review: Chemical Guys Bare Bones – Detailed Image.

For the paint I suggest washing and protecting the paint with a quality sealant. Sealants will protect the paint for 4 - 6 months if you pick up a quality option and do a good job applying it. The Blackfire Wet Diamond with Polycharger is one of my favorite sealants because of it's durable protection and outstanding shine. You simply pour a few drops on your applicator and spread it nice and thin for an even application. Wait 15+ minutes and hand remove the excess with a clean microfiber towel. It will help prevent surface damage and it makes future cleanings easier. If you have any questions please don't hesitate to let me know.
