Default Vehicle Undercoating

I just purchased a very clean Toyota Certified 2013 Avalon in eastern Va. The car will likely end up in Wisconsin as I am moving. The dealer approached me with all this add in stuff including undercoating at $599. I declined. Ten min later she came back and said she had to make her numbers, new offer $399. Looking at the warranty it did not specify what they would do if rust occurred after this treatment, so I questioned her over and over. She basically told me to trust her, yeah sure. What the warranty does say is that if it starts to crack or peel away they will recoat.

The vehicle is still at the dealer getting some minor paint done. She claims she will get the warranty amended to include repair of any rusting after treatment. If so, is it worth the $400?

Wow! You're really moving to Wisconsin! Best of luck TC. I'm not sure if that stuff is snake oil or really necessary.

Hope you like cheese. Buy some good long underwear. Fat girls help in the winter too. All 10 months.

Depends on how long you plan on keeping it. Also depends what the manufacturer has already done to it. For example, my Chev truck has this dumb wax coating that will see warranty work before it expires. My wife’s Honda Pilot looks as good today as it did 6 Wisconsin winters ago.

And who moves to WI???? We are having the largest snowstorm ever recorded in an April. Snow totals ranging from 15-30’’, 40 mph winds, and temps forecasted to stay in the 30s and low 40s for the week.

I sprayed my suburbans everywhere I could with FluidFilm. Pull the inner fenders a little and get it up on the metal backsides...

I highly recommend it . Either from the dealer or do it yourself. The chemicals (squiggly lines on road) that they put on the roads before a snow store will do some damage to your vehicle. It has rusted the brake lines through on my Escalade and older Ram pickup. My new Ram truck has a rubberized coating on many parts that the older truck did not have.

Most rust starts between where panels join and overlap. Under coating does not stop that it just hides rust till it is serious. Spraying the wax rust preventer or fluid film in all the inside of panels especially rocker panels to the extent that is runs out between the weld will help. Spray inside the holes and remove any rubber plugs to get access. Put the plugs back. Undercoating or rustproofing is entry level job at a dealership usually done by someone that doesn't care how well it gets where it needs to be.

Undercoating often traps more salt that it prevents. Also screws up bushings if not applied properly. "MAKE her numbers" means she makes a shitload of money off the $30 "undercoating".

I live in Mich, have never had it done nor would I. I do get car washes quite often that include the undercarriage spray.

Had undercoating done on beach vehicles in the past, & I wouldn't do it again. After a number of years the undercoating dries and cracks trapping water & road salt. As stated above it's not to good on the rubber bushings & body mounts, & makes the vehicle more difficult to work on. Now I get under there once & a while & give spots that look like they need it a light coat of spray paint.

Thanks BWP

Southpaw, where in WI are you? I expect to keep the car at least 5 years, its in perfect shape with low miles. Its starting to sound like that $400 is a waste of money.

The only issue with fluid film is it needs to be annually I believe.

I live just just north of Lake a Winnebago.

It's just another way for the dealer to make money. I never saw any benefit when I lived on Long Island. If you can get to the wheel wells on the Toyota I might try one of the fluid films that are used on outboards. Also along the edge of the rocker panels. And maybe even inside the lower door panels.
That may slow the inevitable rust.
It will be interesting to see how the new aluminum Fords hold up.

I bought a 1997 Toyota Camry new and drove it for 18 years in Michigan, the home of brine-treated roads in winter and summer. Never had the car undercoated or rustproofed, etc. Finally replaced a fender due to rust in 2014. Brake lines and fuel lines rusted out in 2015 and I sold it.

How long do you plan to keep the Avalon? Toyota does a very good job of corrosion protection. Don't have it undercoated- that just accelerates rusting and you'll probably find that West Virginia "warranty" isn't worth anything if you try to make a claim.

I would beg to differ on that one. A simple google search will show they had to replace frames on the trucks due to rusting out in a few years.

That problem didn't extend to their cars.
