Undercarriage protection?

[black bart]

No.

What is PB Blast?
(I'll Google it in a minute.)
Found it. I'll do some research on it.

I"m never without PB Blaster it is the best penetrating oil I have found. :bigups
Never thought about using it for undercarriage it is very thin how long would it last I would think driving in the rain would wash it off.

Yes.
Actually, what I saw that bothered me was mostly suspension parts and springs. The GP is unibody and doesn't have a frame as such, but it has a lot of supports under the body that hold things together. Rear axle, trailing arms, A frames in the front.
Chances are that the body will show rust long before any of those parts actually fail, but they do show some rust.

I hesitate to use any type of abrasive to clean the areas since I might remove enough paint from the painted parts to cause more problem than my efforts would cause good.

Maybe spraying some good old STP on everything would work.
Heck, maybe even some motor oil or a liquid grease would stick for a few months.
The tar like stuff that is available doesn't seem like anything I would want to use.

Sheesh if I'm worrying about this kind of stuff already, it's going to be a looooong winter. :wall

Charles,

I know its a forbidden practice but long ago before my time the old timers used motor oil.You can also get a can of body schutz,or a can of the spray on bed liner at napa.

The oil treatment is a messy way to go and it must be done somewhere that it will soak up "dirt :wow: area".Spray the underside and fender wells and let it run off.Then drive down a dusty road and seal it up.Many old cars were done this way and years later you could still see the oil seeping out of some crevices.I know now green is in but iit works well but the oil and dirt makes for a messy underside.I would say you would be at the powerwash car wash for a while getting the dirty mess off.Total rust protection with a mess after...Every thing has a draw back right.

The second and somewhat cleaner way is this.

The body schutz or bed liner product is a great way to give color and durability to the undercarriage.It sprays on with a gun and drys hard and covers well.The cost per gallon is not that bad either.

Covering after a wire brush is a good way to go.You could sandblast and then cover but that is another messy job.


Just wanted to share some methods used around here...
:howdy

I like that idea. If the bedliner will stick to a rusty surface it would leave a durable covering.
I have used the spray can undercoating and it works well if you redo it every 2 years.

While you're looking at PB Blaster take a look at Flluid Film.Lawn care guys use it to keep grass from building up under the mower decks.I use it on our pressure washing rig to slow down the rust on hose reels,bolts etc.

I'm a big fan of Fluid Film in a variety of applications. It works well at keeping the chute on a snow-blower slippery. I also like it on firearms. It is a heavy bodied aerosol and tends to stay put. That said, I don't think I would use it on the underside of a car. It's too greasy.

That's the problem with anything with oil base its greasy.We all know oily products draw in dust and look like heck afterwards.That's like using armor all on tires and wells,there are better cleaner options available.

Clean the underside and spray with the bed liner and walk away.Another spray can product Charles is HAMMERED PAINT.The stuff goes over rust and sticks quite well.I use this stuff religiously on the undercarriage.It will flake off if you don't wire brush the flakier stuff.The cost is 7-8 bucks per can and works well.We have salt,sand,rocks and the like here at least 6 months a year to contend with.It just needs a touch up every spring and fall...:inspector::idea

Now that I"m retired and I"m home a lot more my vehicles don't wear out they rust out :wall
Combating rust is a Major problem.

When I spray the underside with undercoating I wear paper throw-away overalls that they sell for painting because that stuff will settle down all over you.
