Is this serious rust on a 67 911?

[blau911]

Posting this pic of a rusted battery tray. The rest of the car is spotless - really spotless. Wondering if anyone has had experience dealing with rust repair in this area?
There is literally no sign of any other rust on the car, or any rust in this area when looking at it from the underside of the car. Hoping there is a metal replacement part that could easily deal with this.

Not uncommon for the battery to leak and eat away at the tray. Should be a somewhat straight forward repair of cutting out what is bad and replacing it.

Cut out what you need from the pieces here:

Gas tank support w/ battery tray (1965-68): Restoration Design Inc.

Look real hard directly below that battery tray area the battery acid usually gets in there too !

Be aware that the sheet metal underneath is shaped in a way that carries battery acid to the centerline of the car. There is a hump that keeps it from progressing to the passenger side on later cars, I don't know about early ones. May need to replace a fair bit of metal; the front suspension is attached under there.

Search jimtweet for how to repair it correctly.

Thanks,
Looks like an easy fix then. I have bought replacement metal from Restoration Design back when they were still located in Michigan and the owner seldom picked up the phone because he was a one man business. Times have changed in the past 15 years...

Remove the holey portion.
When you get down to solid, clean up with a wire brush to shiny metal.

Paint several coats of Miracle Paint over & under the shiny metal.
Paint with matching body paint when it hardens.

You can place fiberglass cloth sheets over the holey part and coat with Miracle Paint,
instead of sheet metal.
It will harden like steel with about 3 layers fiberglass impregnated with Miracle Paint.

Hirsch sells the Miracle paint online. Better than the Por15 stuff.

MercedesSource.com sells entire repair kits for under $100. A good guy, Kent Bergsma.
He has free videos on how to repair.

Yes in that it means the rest of the car needs review......

it's a '67, i wouldn't mess around. cut all the bad metal out and replace, it's all readily available.

i just went thru all this on my '74. the acid gets into the cavity and eats the metal from the inside out. i would not be at all surprised if you end up needing to do a good portion of the front pan. i had to replace the entire pan on my car, yet the only visible rust was at the battery. when i cut everything out, the only thing left in some sections was the undercoating, the metal had completely rusted away...

Doesn't look too terrible but rust is like an iceberg sometimes, what is visible is usually not a good indication of how much rust there actually is.

Oh and do not do this:

Every car that I’ve seen with that much rust ends up needing a minimum of 3 pieces replaced up there including the suspension pan. It is extremely labor intensive and takes 70 hours +/- all in plus parts to do properly. I’ve done one that easily took over 100 hours. Of course that’s including restoring all of the coatings and paint on top and bottom of that area.

Yep, and exactly why my 74 has sat under a cover the last two years. It’s not safe to drive and I haven’t had the time to do all the prep and disassembly to take it to the rust man.

blau, is this a car you're thinking of buying?

Oh come on, nothing a couple layers of bondo can't fix !

That was high dollar work. I would hate to see what level of work one gets if they pay less
