Cosmoline..not just for the boat ride across the Atlantic.

[MotoSook]

I know some of us really hate the stuff. I even have a friend who spent an illogical amount of time scrubbing the belly and wheel well of his car to get to the paint. Yes, we hate the stuff, but don't we hate rust too? We should hate rust even more!

So instead of scrubbing the stuff off, why aren't we spraying it on! Without the protective coating, a rock chip or a crack in the paint from an angry wrench will certainly result in rust on the metal under the paint. The clear Cosmoline can easily be desolved with a petroleum based product if a bolt or nut needs to be exposed for repair, unlike that black goop my pops us to spray on the underside of our cars when I was a kid (never mind that the rusty topside of our cars probably needed it more). The Cosmoline won't result in black messy overspray and drip on your driveway or garage floor like the mess my brother-in-law created when he came over to use my lift a couple weekends ago. Argh!

I recently replated all the rear suspension pieces on my Carrera during a suspension rebuild and upgrade. Now I want to clean up all the surface rust on my "Florida car" so I can drive it in the middle of December if I want to. Damn the salt trucks and damn the winter storage blues...I'm getting snow tires! (And who the heck started that myth about Florida cars not rusting....it's just more sneaky rust creeping under paint and weather stripping without a sign of it until the paint starts to bubble in the oddest locations!)

Anyone apply the stuff? I searched for suppliers and it looks like I can get a case of the stuff for about $5 per aerosol can.

I have use the LPS Procyon which goes on using a spray bottle then sets to a caramel kind of goo. I do have a quart of Cosmoline, but its a thick paste that needs to be heated to apply.

RoninLB, posted about the stuff that works and looks like the factory stuff. I just can't remember the name right now. Do a search for the post by RoninLB. Tectal or Tactel, or something like that??????? Good luck!! Tony.

RoninLB is Mr. Cosmoline Wurth Tectyl.

There are others too. Google rust preventive spray.

Here's one of my favorites:

And, here is a source for Tectyl, but which one? There are many choices.

When I had the 1973.5T I wanted to purchase up on the rack for a pre-purchase inspection I was at first stunned to see what I thought at first was an oil soaked transmission! Well it turned out that during the course of the owners restoration, after the tranny was rebuilt it was literally painted with cosmoline, which has the appearance of tar!

The stuff is bullet proof and as hard as a rock. Its a coal tar derivitive and if it deflects rocks and debris from damaging the cooling fins on the tranny, then thats a plus.

Bob, I don't think the black stuff on your T is cosmoline. I wouldn't want to put too thick of a coating on anything that will require service or needs heat transfer for cooling. I wonder if that coal tar derivative you have on your T isn't doing more harm than good.

Here is what I found for the definition of "cosmoline:"

Cosmoline

Cos"mo*line\ (k?z"m?-l?n), n. [Prob. fr. cosmetic + L. oleum oil.] (Chem.) A substance obtained from the residues of the distillation of petroleum, essentially the same as vaseline, but of somewhat stiffer consistency, and consisting of a mixture of the higher paraffines; a kind of petroleum jelly.


This high parafin petroleum distillate is more of what I would describe as the cosmoline I have cleaned off my Carrera and seen on other 911's.

The stuff does a great job of sealing surfaces as there are places on my "Florida car" Carrera that still has the factory applies cosmoline under which is nice and perfect paint.

Craig - your comment about heating it reminds me that I probably have to heat up the garage and car and cosmoline before I spray it on.

Here's where I found some that appears to be the same stuff.

http://www.schafco.com/cosmoline.asp

Cosmoline®
(#24-3160) The rust preventive with 1000's of other uses.
Cleans and protects all metals with a colorless, thin film.
Penetrates to free frozen, corroded parts.
Lubricates to stop squeaks.
Displaces water from surfaces of electrical components.

[Sunroof]

Thanks Souk......but whatever it is its certainly tenacious stuff!! Why is was slopped on the tranny is beyond me because aesthetically, its looks horrible like I ran through a river of black mud and it never came off. Lumpy in places, its there to stay for now. Over the eight years of ownership now, I never had an overheating problem and when I change out my Swepco tranny fluid, it has never looked burnt.

Maybe it was meant to hold the car together

Bob

[MotoSook]

Bob - probably fine until you take the car tot he track...and on the +side...no tranny fluid leaks

[Shaun @ Tru6]

this is great for anything Mg.

TECTYL 846 (or 506) by Valvoline

TECTYL 846 is a solvent cutback, wax base, general purpose, corrosion preventive compound. TECTYL 846 meets the performance requirements of Military Specification MIL-C-16173D, Grade 4. and is excellent for long term protection of metallic surfaces against corrosion in either indoor or outdoor exposure and during domestic and international shipments, like machinery, machine rolls/tools, automatic parts, dies, tubing, and spare parts. TECTYL 846 cures to a dark amber colored, waxy, transparent, firm film.

Surface Preparation:
The maximum performance of TECTYL 846 can be achieved only when the metal surfaces to be protected are clean, dry and free of rust, oil and mill scale. Valvoline recommends that the metal substrate temperature be 10-35 °C at the time of product application.

Application:
TECTYL 846 is formulated to be used as supplied. Ensure uniform consistency prior to use. Continued stirring is generally not required. If the product thickens due to cold storage or loss of solvent during use, contact Valvoline. DO NOT THIN TECTYL 846. Incorrect thinning will affect film build, dry time and product performance. Valvoline recommends that the ambient and product temperature be 10-35°C at the time of product application. TECTYL 846 can be applied by airless spray or brush.

Removal:
TECTYL 846 can be removed with mineral spirits or any similar petroleum solvent, hot alkaline wash or low pressure steam.

Storage:
TECTYL 846 should be stored at temperatures between 10-35 °C. Mild agitation is recommended prior to use. Due to its composition TECTYL 846 can be subject to postproduction viscosity changes during storage. Under proper storage conditions TECTYL 846 can have a shelf life of 3 years minimum.

Caution:
Adequate ventilation is required for cure and to ensure against formation of combustible liquid. THE
PARTIALLY CURED FILM SHOULD NOT BE EXPOSED TO IGNITION SOURCES SUCH AS
FLARES, FLAMES, SPARKS, EXCESSIVE HEAT OR TORCHES. Refer to Valvoline’s
Material Safety Data Sheet for additional handling and first aid information.

Note:
The addition of any product over or under this coating is not recommended. The use of additional coatings could result in chemical incompatibility, thus affecting the performance of this coating as stated in the Typical Properties section. If a primer, other than a Valvoline recommended product is required, written authorization must be obtained from Valvoline.

I've been using Boeshield T-9 made by Boeing for aircraft. It's available in spray cans at most boat stores.

After trying Paint Thinner, Paint Remover, and MEK to clean up my Trans; I found a great way to do it while the car was on Jack Stands. I used two and a half cans of CRC Brake Cleaner. You can watch it run right off leaving bright clean aluminum. This stuff evaporates quickly too. Just don't hit anything with paint on it. Now I can see if I have a leak.
You could then coat it with cosmoline if you want.

[MotoSook]

It appears that the basic product is the same no matter who packages it for market. I suppose the viscousity of the product may vary from brand to brand due to additives, but the base product is a high pararfin petroleum distillate.

I can see a lot of uses for the stuff, so I'll buy myself a case for Christmas

besides running a real nice 964/C2 rear spoiler... & tectyl





what is the name for panel seal gunk?
