Since i'm having trouble with a dying battery (Other Thread), I have removed all the front carpet, spare, and battery for the first time ever (owned the car less than 6 mos).

Does this look like something I need to address? Will this lead to a nightmare if not addressed?





If I should address this, what is the recommended method/process I should perform?

Also, I notice that there's a few holes (visible in the 2nd pic) that lead to the exterior undercarriage. Is this suppose to be like that or is there some type of plug that i'm missing for these holes? If so, do you have a part # and where can I get them?

Thanks!

Guys, i'm finally getting around to addressing this area in my front tub. My question is, does this look like a result of an old leaky battery (current setup is a Optima Yellow) or was it caused by leaking of the brake lines at some point in the past? I do not see any present wetness to indicate an existing brake line leak.

Here are some additional pics I just took.









You see how there's some rust on the bracket? That's why i'm wondering about a brake fluid leak.


My current plan for attack is;

1. wire brush and vacuum loose bits
2. baking soda/water rinse
3. POR15 rust encapsulation
4. white Rustoleum paint.

I'm not sure if I should try Metal Ready (rust converter) between steps 2 and 3.

Any suggestions?

Marc Shaw

Yes.
POR15 recommends to do this before using their paint - I always do all the steps using their products and I have had great results.

I would change #1.

Pick up a package of 3M sanding pads with multiple grits. Patience and a lot of ebow grease.

Please post pics when the project is completed

Mine was rusted through near the battery. I bought that part new from Porsche (the whole bottom panel) and had a body shop weld it in. Not exactly the cheap method, but quite effective. I then installed a dry cell battery so I wouldn't get another battery acid leak and ruin it again.

Word of caution: unless you are a chemist and a corrosion engineer, stick with one brand for all steps, and follow the published instructions exactly. Mix manufacturers, or improvise the application instructions, and you are running a low-budget research project. The better manufacturers are constantly testing formulations and compatibility.

The OP's pictures show surface rust only - no deep pits and definately no perforations yet. Follow the manufacturer's instructions for any reputable coating company, use a non-leaking type of battery, and you will be fine for a very long time.

I ran an Optima red. It got weak after 5 years, but when I changed it, there were no corrosives on top of still-pristine paint.
