cut out or patch over? (rust)

[careyman]

hi guys, hoping for a little advice for a first time (wouldbe) restorer. I have a spot on my ute that im repairing at the mo that is like swiss cheese, its in a spot thats hard to cut out (only the rusty bit) without taking the whole section (least for me) another problem is removing the steel i need to weld to as I`m also a newb (wouldbe) welder .. see pic





Someone told me to just fill in the holes but its thin in parts and it sounds especially bodgy,the question is.... is it going to cause problems if i patch over the "holy metal" (in the future from steel cancer) or do i need to cut it all out (somehow) and start a fresh..

any opinion is a good opinion so thx in advance
cheers Carey

Don't patch over old rusty steel. You're better off cutting it out.

Have a go at making the same shape out of fresh steel, do not cut it out before you make a new section.

Nasty spot ,same as everybody else said , really need to cut it out, and as SunnyTim said I reckon there will be rust under your door rubber , so you need to check this area out and your plenum area.
You will probably have to make it in a few sections and weld it together .
Get your hammer and dolly to work and have a go at making the pieces up , use some .9mm cold rolled steel as it is easy to form into shapes .

Just done this section and I think it is the only bit I didn't take photos of , sorry .
