Have you rust proofed your C?

I did the same thing - it's such a surprise to hear about a dealer not recommending a high profit add-on!

 

I believe I generally agree with the idea of most modern cars not needing rust proofing, so I'd pass. BUT...I don't see how a rust proofing treatment could do any damage to hybrid components.

 

I'm very curious about this as well. The entire underside of my SUV turned entirely to rust a few years back, and it was a 2004. Apparently my rotors rusted out so much that they had to be replaced every 3 years, and I didn't even use the car that much.

Now I just got this car, and I'm afraid it'll happen all over again. You sure rust protection won't be necessary...?

 

I am one who has had every car that I've ever owned rustproofed.

Ask me, if I would recommend commercially applied rustproofing, I would say NO.

I've rustproofed every one of my vehicles on my own. Most all commercially applied rustproofing is an insurance scam.

Good detailed and really effective rustproofing can't be done in 3-4 hours. I spend 8-16 hours over two weeks to do it correctly. I've had cars and other vehicles that last over 15 years or more that have developed only surface rust.

Actually, I've had great success with aerosol cans, like these sold in eBay.



I used five cans and a couple of cans of cheap undercoating to thoroughly rustproof my Prius"v."

The most important thing is to use the wand to spray every cavity first. Then, you go and coat every bolt screw and steel bracket including the brake lines and fittings. The last thing to do is to coat all the body edge joints in the floor pan and the engine compartment and the floor pan.

After a couple of weeks of drying time, then I would undercoat the panels in the floor that would be subject to stone damage. Undercoating is NOT rustproofing. It is basically a "mechanical barrier."

Sixty years of success has shown me that this inexpensive process really works. And, it appears to have been a good animal repellant. too. I really like the benefit that I've NEVER had to deal with corroded and frozen fasteners.
