Corroded Battery Hold-Down

[Sharecropper]

My rear battery hold-down has sever acid corrosion under the rubber coating. The metal frame seems to be OK and should clean up just fine, but in some places the white-powdery corrosion is 1/8" thick beneath the outer rubber coating. I began removing the rubber coating, however soon realized this is going to be a tough, time consuming task. If I could figure out an easy way to remove the rubber coating, I could then sandblast and paint the frame, and try to figure out how to install new rubber coating.

Anybody else had this issue?

Thanks in advance for your comments.

I would like to know what causes this because I've had it too. One battery clean the other covered in white powder. I've had it thick under the rubber coating also.

I wonder if anybody has NOS hold-downs?

You really do not know what causes corrosion in the batt areas? I am sure U do,, first scrape it off with a flat sharp gasket scraper and even a good razor knife, the wire brush navel jelly works fine, i wipe the batt areas down with this stuff let it dry do not rinse then prime with rustoleum rusty mettle primer and let sit for 2 days then rust oleum black top coat, this is good for mettle box"s too, always leave a coat of wd 40 or similar on all mettle surfaces, and baking soda , a dusting on top of batts and in the bottom of the box, will help control the electroalisis and acid vapor that corrodes, all things, just like the instructions of a batt charger say, DO NOT PUT CHARGER OVER BATT WHEN USING CORROSION OF THE UNIT WILL OCCUR.
