Fuzzy magnesium-dow 7 coated

Ok so I bought a new set of Aj valvecovers at a giveaway price. (I wish) 2 weeks old sitting in the trailer are growing white fuzz looks like corrosion coming thru the cover. waxed a few times not much help. Now it is humid here in La but is there a fix for this problem?

 

Fluid Film

I did a little research on the web so take it for what its worth but John Deere store sell a product called Fluid Film that protects magnesium as well as other metals although it does leave a film on the metal.

We spray ours with Kroil it stops the fuzzies.

 

What's Kroil and where do you get it? Thanks, Mark.

 

Its a penatrating lube/rust prevenative, about like WD-40 but I think its better. I found it through a Caterpiller mechanic.

Its hard to find in stores, but you can order direct ph# 615-833-4101

Website is www.kanolabs.com

 

KROIL is an excellent penetrate! Its the best I have ever seen , It is all GE lets us uses on gas turbines and they claim that it will creep to the millionth of an inch BUT.....

IT IS NOT MUCH OF A RUST PREVENATIVE ! I made the mistake of scotchbrighting and the frame of my car and wiping it down with Kroil and when I came back in the garage a couple of days latter the whole frame was brown with surface rust

 

It does evaporate away, there is probably something better. Ive used WD-40 too.

 

the guy on roadsters.com swears by Gibbs Brand Penetrating oil on magnesium wheels, valves covers etc

Has anyone tried spraying standard clear coat on em?

 

are they dow 7? that will help some..I have been using my blower spray on them seems to be working..Dave

 

Still say if you don't mind a yellowish hue till it soaks in

then fluid film is the stuff to use.

(Free-Press-Release.com) September 20, 2005 -- Testing was done in an outside testing facility according to Salt Spray resistance - ASTM B117 standards where Fluid Film� was tested against WD-40, CRC 3-36, Corrosion X and LPS-3. After 3 weeks exposure Fluid Film� had a total surface corrosion of 1%, while the closest competitor contained 40% surface corrosion. Two of the other competitors had achieved 100% surface corrosion during this same period, proving once again the superior quality of Fluid Film�.

Fluid Film� has also been tested by the Department of the Navy who conducted testing on maintenance products for Navy vessels, and Fluid Film� was found to provide superior performance. In fact, according to the Naval Surface Warfare Center, Carderock Division, Philadelphia, PA where material testing took place, the difference performance...profound...most telling result of all the testing accomplished for this project." The Naval Ammunition Depot in Pensacola Florida conducted tests to find safer products for corrosion preventatives, and Fluid Film� was found to supply superior protection in salt water environments. Furthermore, the test results found "outstanding results" in direct exposure to the outside environment, and concluded with these findings: "The results of the tests preformed indicate a superiority in Fluid Film� for long term corrosion protection. The properties of Fluid Film� help to achieve a more environmentally safe work place."

Fluid Film� was further tested by the U.S. Air Force in accordance with Mil-C-16173-E Grade 2, and was found to exceed all requirements. Delta Airlines wrote a process standard recommending Fluid Film� as a general purpose maintenance lubricant, stating that �Fluid Film� differs from other general purpose maintenance lubricants in that the lubricating capability remains for extended periods of time and is not subject to evaporation.� Studies conducted by Purdue University found Fluid Film� to protect against stress corrosion cracking. When applied prior to exposure of the protected surface to an aggressive environment, Fluid Film� was most effective. Boeing�s Space Systems Division wrote a specification for Fluid Film�s use on the Space Shuttle after Fluid Film� passed the rigid testing standards for maintenance materials. Fluid Film� was also tested by Boeing�s Engineering Materials and Process Laboratory and found to be twice as effective as commonly used CPC�s for aluminum alloys. Sundstrand Aerospace wrote a specification for Fluid Film�s use as a preservative oil for magnesium, which is now used as a standard throughout the helicopter industry. The U.S. Coast Guard wrote an engineering specification for Fluid Film� with the purpose being to improve the corrosion resistance of corrosion prone areas of aircraft.

With test results like these, it�s amazing that Fluid Film� is not the number one rust/corrosion preventive and lubricant on the market today. Eureka Chemical Company has been around for over 50 years, quietly supplying the military and industrial markets with its superior quality product line. Fluid Film is now available to the consumer through a network of dealers and distributors. You can find a dealer locator on their web site at www.eurekafluidfilm.com.

 

yep dow coated, new covers about 3 weeks old

 

Ditto on the Gibbs, I've been using it on bare chrome-moly for over a year and it has done the job quite well.

Also, you can find it on Ebay cheaper than most places.
