Rustproofing

Does anyone have any thoughts on the value of rustproofing? I just traded a 2011 for a 2014 GC and I am considering having it treated with the Krown spray which costs $129 CAD and must be re-applied annually to maintain its warranty. My last GC had four applications. I have a track record of only keeping a vehicle until it's warranty (100,000 km) runs out but being a senior I am starting to think about keeping vehicles longer. The dealer's rustproofing is much too expensive for a one-time application.

I live in a City which lays out tons of road salt as soon as frost appears.

Re: Rustproofing

If you're asking for opinions, here's mine. Rustproofing is a waste of money. Keep your vehicle clean, especially the undercarriage, and save your money. I'm sure others will disagree with me, but that's my story, and I'm sticking to it.

If you do get rust proofing purchase it for its sound deadening qualities not its ability to stop rust. Truthfully, when was the last time you saw rust on a vehicle that anybody reasonably took care of?

As much as I hate to do this, I agree with Jack.

Re: Rustproofing

I don't give much value to rust proofing........as someone else said, if you take care of the vehicle I doubt it's going to be an issue. I'd rather spend that annual fee on either a detailer if you aren't into doing it yourself or some quality sealants or detailers.

Re: Rustproofing

Appreciate everyone's opinion. Had my last Jeep sprayed four times and I feel that I threw money away as it was in near showroom condition when I traded.

Re: Rustproofing

Find a brushless touchless car wash with an undercarriage spray option. Had several cars in Illinois (another 'salty' state) and never had a problem with rust.

If I drove it in the snow or slush, I would run it through the car wash every couple of weeks. Cheap insurance and keeps the car looking nice as well!

Other than salt season, I always hand washed the car.

Re: Rustproofing

I used to undercoat all of my Jeeps up until the last couple I had. For the most part it's a waste of money.

Never had undercoating on my 02 and it went through 12 winters worth of road salt. Never made any effort to spray off the underside other than to run it through puddles. It remained remarkably clean and rust free.

The only place I could seriously recommend rustproofing would be inside the doors. A lot of crap drains down inside there. Even though there are drain holes in the bottom, a lot of road salt collects in there and eventually it starts rusting from the inside out along the bottom seams.

Re: Rustproofing

From what I have read here, I think I will skip the rustproofing and continue keeping my GC clean.

Modern vehicles such as JGC are fully dipped now days so aftermarket rust proofing are of limited value
Remember even id the vehicle has been dripped, rust may occur where you chit off that level of protection
So touch up rust application is good as on going maintainence.

I'd agree. Locate the best no-touch wash with the biggest blasting underbody wash you can find, and use it.

I also suggest a wand type for under hood... if folks used that, the brake booster recall probably would not have been needed.

If you have a home power washer, there are curved wands you can get to make underneath a lot easier.
