sayporscha, I see where you are using a post relocator on your optima. Where did you find that? I would love to use those on my optima...

The POR15 suggestion may be one to look into as well. Their products are really great! I just sealed up my whole battery tray area!

I just ordered the sample kit, the cloth, and the por15 paste. I have a really bad crack in the tray, so I threw in the paste just in case.

That's one of those battery disconnect gizmos. I got it from Harbor Freight Tools, but I've seen them in aftermarket calalogs. You can see it laying in the rusty battery tray before the repair.

Yes, That paste is definately worth while. I used that too for a final coating in all of the corners (and one solid coating over the patch itself). I have pix that I can upload of the whole process if any one is interested. Once again treat this stuff with extra caution (mustard and a white shirt...).

Good luck

Mrwolfe, feel free to upload away!

I would also like to see the pictures / process.

Here are a few of the pictures that show the damage and preparation for the Por15 to my battery compartment. I still need to pull the other pics off of my camera that deal with the actual fix. But hopefully this will give you an idea of the type of repair I had to make. Stay tuned...

Wow. If you were able to fix yours, then I should be able to fix mine.

You better tape up that fender too! POR15 IS NOT FUN TO REMOVE!!!!!!!!

It will turn out awesome though. POR15 is great.

Your description sounds exactly like mine which I fixed yesterday. Took me about 2 hours. I fixed mine with some Marine Tex and fiberglass mat. I've welded patches, used fiberglass resin, POR 15, and all are good for different uses. Marine Tex (which you can get at any boaters supply store), is totally waterproof and gives you about 15 minutes of working time unlike fiberglass resin/bondo etc. Used along with fiberglass mat, it makes a super strong bond and is impervious to many chemicals so that is why it's great for a battery tray repair and in my fenderwell.

I simply grinded the bad areas down to bare metal after I scraped off the rubbery underecoating Porsche put on (I found that hole the sizre of a coin and the punch out was still there-why did Porsche put this there?) Also found that the front area you described just like mine rusted through into the inner fenderwell also, so I removed the wheel and also ground that area down to bare metal. Sprayed all the areas with rust converter you can get at any parts parts store and let dry for about 30 minutes. Cut some fiberglass mat to cover the holes and mixed the Marine Tex and applied to both sides of the mat and placed over the holes. Also put the Marine tex over any bare metal areas with a spreader and along the seam of the tray on the outer edge. Since this stuff is waterproof, rust won't reappear a couple of years later.

Mine was very bad and I used fiberglass. It worked great! Good luck!

You bet it did. Por15 definately has my vote. And your right about covering up the fender. I laid several old towels over everything. Soon as I pull my other photos down I will upload the final results.

I found a small hole about the size of a dime or so around the front section of the tray.
I do not have a dremel, would a metal scraper work fine? I have access to a 1" scraper from my work which we normally sell to sand/finishers for hardwood flooring jobs. My plan was to use a scraper and a wire brush to get everything down to clean/bare metal first before I start using products.

Post pics of the process if anyone has.

Thanks guys

This 6 year thread revival makes me wonder, WHERE ARE THE PICS MRWOLFE??
