Battery area rust repair - acid neutralizer needed?

[RichMason]

Inspired by the detailed posts last week on relocating the battery, I went ahead and moved mine to the rear trunk. I took out the sound pad and the FI brain, exposing the "hell hole" as JP Stein calls it and boy is it a mess. I'm going to vacumn and sand and POR-15/Extend it so I can see the extent of the damage and stop it from expanding. My question is, is it necessary to use any sort of acid neutralizer to stop continuing corrosion from residual battery acid? If so, can anyone recommend a product?

Thanks

I might would try Naval Jelly on all rusty areas after sanding to get to the nooks and crannies where sand paper and maybe even sand blasting can't reach. Then maybe a bath with Baking Soda to neutralize the acid. Then use the POR - 15.

Check out www.por15.com
They have all the products needed to clean, convert, and seal rust. I am in the process of using their system now and it works as good as any of the others I have used.

I would use the baking soda first. Rinse with water and then do the rust removal. Guess it depends on how bad it all is. Seems on my car everytime I get after the orange demon I have new air inlets. But the metal prep and POR-15 does the job pretty well. Hey does anybody know the structural strength of this stuff? just kidding.

Plain old Arm and Hammer Baking Soda mixed with water will neutralize any acid. Make sure you get all the hidden spaces. It might not hurt to wear some safety glasses and this stuff reacts with the acid in a pretty violent manner. A breathing filter would also be appropriate.
