Fixing a rust patch

[lolsteve]

splashed a bit of primer on just for tonight in case of rain

Balls to the wall, good man!

Cheers, need to just get on with it now rather than umming and arring

Yep, need to get all the way back to smooth, untouched metal, all that there wants chopping out.

Problem is there's no access under the hole to weld since there's a duct(?) running underneath meaning would have to cut out everything. Think it's just going to have to be a case of sand back as much as I can and put a thing layer of filler on, like butter on toast
