i was gutting my car to turn it into a drag car when i found this...


how can i fix this?

 

With an air cut-off tool, a piece of sheet metal, a hammer, and a welder.

 

Would the welder not just melt the body? Or could u just lower the temp?

 

Do you have a MIG welder, or know someone with one? You need to cut out the rusty metal....rust never sleeps! Shape a new piece, and weld it in. MIG is made for sheet metal. But you need to get all of the flammables (like the pad in your hand) way out of the way so you don't start a carbeque.

 

That carpet and insulation are all out of the way already. I know some one who has a mig welder though. I never thought of that but thanks. Would you suggest grinding to make it pretty? OR will it ruin the weld?

 

As long as you get a good penetrating weld, then you can grind away till it's smooth and "pretty"! Be sure to get the metal good and clean where the weld is so you don't get an ugly splattered weld.

 

Didn't you say you work at a body shop?

 

Option 1
I think you can get patch pannels if the holes are smaller you can just get some 18 gage sheet metal. I like the butt weld. Flange welding is not uncommon in floor repair as long as it will not be a show car.

Option 2 Cut away all the rust and cut out a patch pannel about 1/2-3/4 larger then the hole you cut. Get some Body pannel epoxy from a paint supply store and glue that bad boy down. It would be just as strong as the above repair but not as pretty.

Option 3 Cut away all the rust and cut out a patch pannel about 1/2-3/4 larger then the hole you cut. Drill screw hole thru both the floor and the pannel. Remove the pannel put a bead of silicone all the way around and use sheet metal screw. Not as strong as the above repairs but will pass most safty inspection

Option 4 Steal a road sign, wedge in the back and stomp it into shape. You should pull the carpet up first. Once you got it good and stomped go git you some of that thick driveway tar. You know the stuff that fills them cracks. Get a big ol brush then just gob up the whole underneath. Bam its ready for craigs list

Option 5: Slop some bondo in there and call it good...enough.
Option 6: Chew up a huge wad of bubble gum and flatten it out to make a patch. You ever try to get that stuff off a sidewalk?
Options 7-10: Duct Tape!!!


Those were the comments I got for my rust problem......

 

Yea but i never messed with rust i just did body kits bondo, and fiberglass. lmao

 

New floor pan, or some new sheet metal welded in...
