requirements on my last house were: big garage, flat concrete driveway, flat yard. makes life easier.

"not on gravel road" wasn't on my list, but that was implied.

OK, big difference between "dirty" and "corrosive". Permission revoked. In fact, perhaps you should keep the car at your mom's place.

Does this need to be said? For cars you want to keep for a while, or sell to someone who looks underneath:

1. Under no circumstances should you drive on treated roads; beware: sand may have salt in it.
2. Do not park (or live) downwind from the ocean.
3. Avoid all other corrosive substances, e.g., lime, or the acid pickling shed where I used to work.
4. If inadvertently exposed, go for a drive on a rainy day as soon as possible afterwards (but not if you live near Sudbury, Ontario, of course).

Every car wash I've used has an under body option. It's the only reason why I ever use them.

The Deputy

This cost an extra couple bucks at ours in town...so it is out of the question...lol

Funny story.

I drove old blacky to work yesterday and since we have a drive-thru wash at our garage...I decide to take the car through. Well, I don't know what the deal was...but when it came to the rinse portion...no rinse. So, there sat the car on the street side of the wash bay...covered in soap. There are sensors in the cement and I'm unsure if there is enough metal in this car to set them off...it is primarily designed or set up for dump trucks and buses. Anyhow, there I am...big as life...trying to get my car rinsed off with a hose before the mega boss happen to drive by...lol.

My wife was suppose to take the 928 to the horse barn today (since the owner's husband is a car guy and has several muscle cars in "his" stable)...but the road grader came down the road this morning...so I told her the deal was off. Told her..."If some ****wipe comes flying by you and puts a rock through the window and I'll be insane and it would be "John Wick" all over again...

Yes, gravel roads stink...but to not have any neighbors closer than a mile in both directions...is worth the challenges.

Shoulda mentioned this in your original angst-riddled post!

The Deputy

And where is the fun in that...

I live in Scotland where we salt the roads so I can understand. My car is a bit of a mess underside despite being a fair weather car during mine and the po ownership as far as I know. I've started replacing some parts out and am also using an oil based rust inhibitor called corrosion block by acf-50 which I generally add more of every time I have the car raised. Also going to add an underbody steam clean or two to my maintenance schedule. Not sure about lime though.

The Deputy

This rust inhibitor...does it leave a tacky residue? We see tons of salt all winter long year in southeastern Michigan. I was fortunate and my 928 had never seen any salt and was garage kept for its entire life. I was very surprised while doing odd fixes underneath and how well things came apart, especially for being a 31 year old car.

Not tacky like the wax based inhibitors. It's oil based with a similar consistently to atf oil. Wax based is supposed to be good for new metal with no existing rust but will lock rust in if it already exists. Oil based is supposed to penetrate existing rust and slow it down.

The Deputy

Thank you, for the info. I will be taking the car to work Friday and giving the bottom, wheels off and inner fender wells off, good cleaning. Maybe after it dries properly...I will apply this product in places I deem necessary.

Darn it...I just looked online and Amazon has it. Just ordered some stuff the other day...would have been nice to lump this into the shipping. Darn!

Brian.

The Deputy

My wife mentions doing this all the time...moving somewhere she would be happier...but it has nothing to do with the car or the road...lol

Get the blue corrosion block stuff as opposed to the original pink coloured acf-50. This is a little thicker and is supposed to give up to 2 years protection as opposed to 1. Think it is more designed for aquatic use so should hold up ok on the underside of a car. Would also recommend getting the litre bottle as opposed to the spray cans. I use a hand held plant sprayer to distribute it which is ok but think a powered spray gun would get a better mist. Avoid getting it on brakes and tyres obviously.

Huh? ... to keep sunlight off the car in the garage?

I keep mine in a dark fully lined garage away from the sun, open the door, and then make sure I drive them fast enough to blow any dust off ... simple

The Deputy

I'm assuming he has windows in his garage, like I do. The late afternoon sun boiling through those panes of glass could start a bale of straw on fire sometimes, it gets that intense. So, I keep my car covered inside for that reason...beside dust issues.

I do like the driving fast idea for dust removal though...although, l believe l'll just go ahead and try it without running it past my wife for approval...lol.

Brian.

The Deputy

Great info.
