What do people think about rustproofing? Is it worth having underbody rustproofing protection (like that offered by Ziebart) applied to a new IS? I'm planning to keep the car for about 7 years and live in the Washington, DC area. Thanks for any opinions.

 

the paint/primer asks as rustproofing...there's is no need for it...its actually useless on pretty much any current car.

it's mainly for old cars that have bare chassis.

 

isn't there a 7 year rust warranty from Lexus??

 

What he said...

 

Being in Canada....I swear by rust-proofing. Much depends on several factors....how long do you plan on keeping the car, will it be exposed to alot of salt during the winter months & the actual rust-proofing product itself as there are many available.

I get all my cars (and family too) done every couple of years (even for the 'permanent' products). The product I use is called 'sym-tech' & it's a yellow paste type product that has been around for decades & improved during that time too.

I'll put it this way......I owned a 1991 Olds Delta 88 Brougham as my first car during the mid to late 90's....& did this religiously....I still see the car on the road from time to time & the body is in excellent condition. I just wish the current owner maintained it better lol.

Never get it done at the dealer.....they bend people over the barrel as it's a huge profit for them ($1,000+ for the 'package' is not uncommon). I pay cash under the table at the shop I use & save close to 80%.

I've heard many arguements from actual dealers sales staff that tell you never to have this done (and it might even void the factory warranty!).....as soon as I get in the 'business office' to buy the car, it's one of the first things they try to sell me (after that extended warranty).
