Rustproofing - Let's discuss..
Just wanted to see how many fellow fbody owners have taken the plunge and rust proofed the undercarriage of their vehicles. I've finally had the oppotunity to check out the undercarriage of mine, and it's a mess to say the least. I have brake lines, springs, frame rail, and gas tank surface rust already well on it's way. Honestly, the undercarriage of my car suggests the car is twice as old as it actually is - which was tough to swallow after finally seeing it. Like many fbody owners here, I take great pride in the overall condition of my vehicle. I truly plan on it being my "forever" summer car. I've been looking into possible rustproofing remedies but I'm simply not sure which one to do. I've debated bringing it to a body shop to see if I could have the surface rust sanded down then protected with some type of undercoating. Has anyone here done this sort of work or paid to have this type of work completed? I found a local place that does rustproofing undercoating for $200 + $40 respray suggested once a year thereafter. Any suggestions/ideas?
Any chance anyone had this type of work done and has before/after pictures?
D&M Corvette also supposedly offers some "restoration" type service that addresses rust issues.

The problem with rustproofing an already older rusty car is that it really doesn't accomplish anything. The rust will still be underneath unless you are talking about totally removing the old rust first. A full restoration?? Not likely. Save your $$ and just keep the undercarriage as clean as possible. That $200 quote will be nothing. $2,000 would be more like it for a proper job.
**Just a side note. My T/A is a one owner (me) and it is garage kept and has only 29,000 miles. Despite always keeping it clean underneath, there are still issues. Not serious at all but just normal aging and use. Last year I picked up my '07 Mustang with just 3,000 miles on it. Garage kept by a collector who had 12 cars. There is surface rust in many areas underneath. Sometimes it just can't be avoided. All I'm doing is keeping it clean and free from future dirt accumulation, etc.. but not spending any $$ on rustproofing.

I know there are some products by POR15 and Rustoleum that are advertised to do a variety of things, depending on the product in question, ranging from painting directly over existing rust to stop it from expanding, turning already existing areas black, and rubber undercoatings?

I'd be much more inclined to do this project myself than have some company spray whatever they are trying to pass off as rust proofing...having to respray once a year should tell you a little bit about the durability of what they're trying to push. POR-15 lasts a long, LONG time.

Do a search for POR15, and you'll likely find many people that have used it with great success. The most common application is probably on the rear end, which always turn to rust. It's very good stuff, and is supposed to mechanically (not chemically) keep the rust from spreading or coming back. Like anything else involving paint, prep work is the key.

There's a few other out there beside POR15, somethat require less prep. I did some research last year, and the one that I liked was called "Rust Bullet". There's another one out there, that's similar, I forget the name.
I really need to pickup some of this and do my car too, I was just underneath there yesterday installing a catback, and it's looking bad, and is starting to progress beyond merely just surface rust.
edit: here's a little article on Rust Bullet that I had in my favorites. What I like about it is the lack of necessary prep. Basically just wire brush or wheel the loose stuff off. http://www.customrodder.com/tech/030...tor/index.html

My solution to this was to buy a second F-body for more regular use. The nice one just stays in the garage now, only coming out for the occasional show or perfect weather drive. Even on my garage queen, which has never been driven in rain, the bare metal areas still develop some minor surface rust (axle, uncoated bolts, etc.).....nothing of concern though.

i used an eastwood product that has an 18 inch spray nozzle on it that fits into frame rails etc. the stuff has a self etching agent in it and worked good inside the frame horns its o.d. green when dry. i use an old restorer trick when my car is parked for a long time in the garage, i.e. winter storage i lay painters plastic down on the floor as a vapor barrier because here in the mid west the concrete floors weep humidity and cause condensation. lowes and home depo have it cheap, but it needs to be a little thicker

I use rubber lined carpet for this same reason. It's a bit easier to deal with than plastic sheeting.

My T/A has some of your typical surface rust on its underside. I plan to attack it with a wire wheel and some POR15, or one of the products similar to it. I haven't done much research one which one would work best for this application.

Mine doesnt have any rustproofing, thank god it doesnt & really very little rust anywhere. I found a few small spots on the body & very slight surface rust on a few of the fuel line fittings. Brake & fuel lines are rust free. My front lower control arms have surface rust. My car has never seen a winter & its stored inside but no plastic underneath. If your car has bad undercarriage rust it obviously has been driven through snow, salt & slush to look like that.

Amsoil has a good undercoating spray. I used it on my daily driver which I do drive during winter months and actually it has done a pretty good job so far. It's relatively cheap at $8 a can, and you will probably use ABOUT 2 cans for the whole underside of the car. Respray once a year if driven in winter, otherwise I would respray once every two years.
