no replacement pannel for that im afraid. realy look the car over good, theres a few spots that rust likes too hide on these cars like under/on the bottom of the door itself by the weatherstripping. im not realy an auto body guy but id say the best bet would too cut it out and put some good metal in there. seems that rust finds its way back relitivally easily otherwise....good luck with her! and welcome....

Yep. Your best bet is to cut that section out and weld in fresh metal.

About the only thing that would work besides welding in a new panel would be a POR-15 product for rust repair. I've never used it so I couldn't say from experience how well it would work. I've heard that it's some pretty neat stuff though.

so how mutch por-15 would be needed to do a whole underside and up to the trim on our cars? also has anyone used the tank sealer? i know i have a slight gas leah only when its full. like a drop or 2 every few minuits. so i was thinking when the car sat just taking the tank out completely draning it then using that tank sealer on it. any ideas?

After a quick google, this is what I found:

[COLOR="Red"]*All estimates below are made using one coat on the area being treated; however, we recommend two coats in most applications.[/COLOR]

POR-15 application on non porous surfaces (most metals):
Approximate coverage:

* Pint = 50 sq. ft.
* Quart = 96 sq. ft.
* Gallon = 350 sq. ft.

[COLOR="Red"]Engine Enamels:[/COLOR] One pint will cover any standard automobile engine block

[COLOR="Red"]Hi-Temperature Paints (Factory Manifold Grey, Black Velvet, POR-20):[/COLOR] For exhaust components 8oz. will coat an average set of manifolds and a small set of headers.

[COLOR="Red"]Color Chrome:[/COLOR] Color Chrome Pint Kit will cover five rims

[COLOR="Red"]Floor pan and Trunk Kit:[/COLOR] Enough products to do two floor pans or one entire trunk

[COLOR="Red"]Auto Fuel Tank Repair Kit:[/COLOR] Seals up to a 25 Gal. tank

Hope that helps.

I'm not sure I understand your question. All I know is you have to brush it on and it bonds with the metal to block out oxygen. And from what I've read, the rustier the surface the better. Just have to remove the loose stuff before you apply it.

Hit it with a wire brush to get the loose stuff off, make sure everythings dry and brush/spray it on.

For ther gas tank I think i'd rather find a good tank and toss it in

The POR-15 works. I used iton a spot that came up about a year ago on the very bottom of my left rocker panel. Hasn't caome back thankfully. Apply a couple of coats, sand lightly and paint over it with a good match. You won't be disappointed;)

now its decent to use as a primer correct? cuz i figure use por 15 as a primer under the paint so that would furter protect your car.

I think I remember hearing that it doesnt bond too well to bare steel, it uses the crusty rust to hold on to... i'll try to find some more info

Some very good info in here, you gotta dig for it though!

tbirdscott is right. For bare metal, you have to use the por-15 prep. They sell whole kits though that come with everything you need.

As for the gas tank repair, I don't understand why you would go through the hassle of dropping the tank to do a repair that might last a couple of weeks. Do it right, do it once. Replace the tank.:D
