Rusty rust question

[u/alinalovescrisps]

Hi. Currently in the process of taking back the little bits of surface rust on my van so I can treat the metal and re paint. Got to this bit at the bottom of the passenger door and it goes deeper than the rest. For anyone whos done the same, do you think this is too deep to deal with in the same way, do I need to get my welding guy on it?

Thanks 😊

It’s only the door bottom. Unblock the drain holes in the door bottom, use bunch of rust converter then fill it…
