Rust Removal

[TKO]

I got a 20c sized spot rust on my driver side A-pillar, located on the surface which face the door.

Just wondering how hard is it to fix it DIY style or is it better to go to a pannel shop.

Could someone please provide information on how to take it out DIY style.

Your help is much Appreciated.

If you have to ask; you can't do this...

Depends if its surface rust or deep rust or a hole
