MSD distributor

Our distributor did the same thing. Spent way more time cleaning the corrosion mess up than I wanted to. Per someone elses comment, Zinc-Aluminum coating of internal components will only last so long. Zinc is a sacrificial element which the corrosion will attack until the zinc gets eaten through, now it is eating the bare metal again and it doesn't last all that long. They need a more robust coating that contains zinc as well as a hexavalent chrome such as a zinc dichromate coating. The chromium element is one of the best rust inhibitors around but, the EPA is forcing industries in the USA to stop using hexavalant chromes in their coatings. I don't know of any other coating the EPA approves that does a good job of preventing corrosion as hex chromes.

Well, we have people from all walks of life. Any suggestions from outside the box to use as a rust preventative in our MSD distributors ?

I will throw one out there to start. EEZOX mainly used to prevent rust on pistols and rifles. Goes on wet and dries to protect from rust. This as a metal treatment and did very well in a 2 % salt water spray test. After the initial treatment, salt spray actually beaded upon the metal. Cheap, comes in a can. Has anybody had any experience with this product ?

I am curious if anyone has painted their cleaned up pick-up with nail polish ? Somewhere I read about using nail polish top coat (clear).

I would not recommend nail polish.
The best solution would be using a dielectric conformal coating as used on circuit boards and electronics. There are several available commercially that will sustain an alkaline and high temperature environment. The coatings are available brushable, spray and also in a pen.

This comes from my sons dirt track car that has to run a HEI. Always had corrosion on the contacts, this year I listened to tec west and filed everything to a point and made sure the dist was phased in to a nats butt, but when the cap was popped off this fall it looked like a new unit. Luck or weird science. Tom
