Need To Fix Rust

[machg]

Yes thats what I did with the running board,

With the rear quarter bottom pictured above i would use the recess on the top bend the 20mm around into the wheel arch curve the bottom then 2 sharp bends in a folder and overlap like a door skin. then at the bottom and weld at the back so it looks as the original panel.

 

I fully understand your general recessing principle, but it seems to make fabrication a lot more difficult (especially if you don't have the specialist tools). Could you achieve the same sort of result using two patches, one cut to fit the hole neatly, and another larger one to tack (or tack and seam weld?) in behind? What would be the advantages/disadvantages of using two patches? Cheers, Mark G.

I would go with a section out of anthoer vehicle with no rust.

 

How i do it is remove the old rust section in one piece, cover it with masking tape and mark the edges and returns as locators.

I then remove the tape place it on the new section, line it up and simply cut along the marked edge.

For me this works and gives the new section an exact fit as it is the same size as the removed one.

 

Hope this info can help.

WTF ?

 

the cut out is a little rough but can be fixed, You just need to take a bit more care fabricating some patch's to fit the holes if in doubt do smaller patch's.

like i said, not my handy work. i went inside quickly and came back out to that :lol:

 

i know it can be salvaged, just i lack the skills to do it, and i refuse to let my friend try again......ever.

well he was on the right track it looks like he can weld ok? the left looks like an easy fix maybe you should fabricate the patch yourself pop rivet in place then get your mate to weld it practice the left first ready for the right.

[oh what a nissan feeling!]

looks like he is roughly on the right track.

 

You are going to have to remove that bumper to make it easier to get the welder in there.

 

Also, on the rear of the car there is a factory seam there (from memory),

try to replicate the seam back there to give a neat finish.
