this afternoon I started to remove all the rust from the rocker panel
it was way worst than expected but nothing a few piece of metal, welding and finition bondo can't fix
I grinded until I was on solid and clean metal and shooted everything with a thick rust proofing paint

I have no after pictures of the driver side , the passenger side is the worst

if you car has some visible rust at the same spot as mine double check everything
because I found out that the plastic paint/protection we have on the lower rocker panel is perfect to hide the rust and keep the rotten metal in place holding there until  you see it too late

i thoght avengers never rusted lol

and wow, thats some nasty hidden rust

I'll second that!  Many pounds of rusted metal were cut out of the exact same places on mine when it was at the body shop.
