Rejuvenation of Battery Box

In preparation for installation of two new 6TL batteries to power the M1038, we removed the battery hold downs and tray to see the extent of acid damage on the aluminum.

Although there was extensive corrosion evident, the CARC seemed to provide a lot of protection from the acid. After spending considerable hours scraping, wire brushing and using a “scruffing” pad on a small air grinder, we applied several passes of baking soda and water to neutralize any remaining acid.

After thoroughly flushing and drying the surface, etching primer was applied and let dry. We debated about final coating and went with rubberized undercoating. This material is definitely acid resistant. And it appears that the box may have been originally coated with rubberized undercoating from the Marines.

We will next remove the shunt and mask off the entire battery box to be coated with the rubberized undercoating.
