Corrosion protection info

[Mike Rohaley]

I thought that the following product may be of interest to the whole group considering that many / most of our cars use a steel space frame with riveted aluminum sheet. As you most likely know, this arrangement has one major downside which is the electrolytic action between the two metals ultimately reducing the aluminum to a crusty white powder.

 

I have been conscious of this issue since I purchased my car and have used WD-40 liberally each winter to diplace the moisture between the panels and frame to at least slow down the eventual corrosion. But I knew that once corrosion started there would be only one solution (reskin the car). Apparently, the proper solution to this has been available from the aviation industry to prevent (and stop existing) corrosion in airframes, it is called ACF-50.

 

This link has a good description of the product: http://www.learchem.com/images/Tech%20Spec.pdf

 

This is an independent test report on the performance of the product: http://www.corrosion-control.com/CorrosionAbatementReport.pdf

 

The best pricing that I have found so far is from www.aircraftspruce.com . I have done some further research to find similar products but this one clearly looks like the best of them. If you are like me in that you want your car to exist 50 or 100 years from now, applying this product every 24 months might actually make that possible. I just wish I learned of it 5 years ago.

Thanks, Mike. I will order some once the holiday hub-bub dies down.

Just what I was looking for. I was thinking about some type of coating for the underside of the car but was worried about adding weight. This product should take care of the problem. I ordered up an aerosol can of it, thanks for letting us know about it.

Good research Mike, thanks! That's definitely on the to-do list for this winter. I've ordered from Aircraft Spruce in the past and have been very pleased with their products and service.

Guys,

 

I sell a material designed to prevent corrosion during long term storage or global shipping. I am looking into offering the product to the automotive enthusiast market as a means to control corrosion on spare parts. Think spare block, cranks, wheels, etc. Would this be of any interest to you? The product is a bag that the spare part is placed in, the bag is closed, and its contents are protected from corrosion. No need for sprays or VCI. It is currently used by NASA, BMW, Rolls-Royce, Ford, Cat.

 

It does a spectacular job in the markets we currently sell into, and I am trying to gauge the interest in the enthusiast market for a high quality solution to long term spare part storage. What do you all think? :bigears:

My main worry is to protect the parts that are currently in use out in the elements and the product you have will only apply to my few spare parts. The spares such as wheel bearings are sealed from the manufacturer, does your product add some level of protection over and above that?

 

For me personally the need seems rather limited but there are probably a few other people who could use what you have. Please post some further information, maybe it's a product I didn't even know I needed.

Mike,

 

Thanks for the reply. I put up some info when I get back in town.

 

The idea started because I had about 6 cars worth of Datsun 1600 and 2000 roadster parts sitting in a storage trailor. While they were not sitting outside, there was still an issue with spare cranks and engine blocks rusting. I know there are guys out there with garages full of spares and swap meet parts that are rusting, so I thought it was worth exploring.

 

To answer your question - yes our material exceeds the typical packaging protection. As an example, it is currently used to store gearboxes for Mini Coopers. By German law any manufacturer is required to supply an OE part for 15 years. This particular gearbox manufacturer was closing down and had to find a way to store the trannys for 15 years. Our material is the only product capable of meeting that requirement.

 

My goal is not to sell you guys on the material, just gauge interest. I'll put the info up after the holidays and look for further feedback.
