my car failed mot on door sills and bit of welding near rear arch by axle is there any way i could patch this up for a little bit till i save up the money to get it done say couple months as only just passed my driving test and my pride and joy is sitting on me driveway and im still using the bus lol cheers

 

The only cheap way of doing it is to plate it rather than cut out the rot and repair it properly.

 

how do i plate it then mate cheers

 

Weld patches over the affected parts.......

 

i did this once on my old work sierra the bottoms of the doors rotted out, welded sheet patches over the rot and it passed.

 

Rotten doors would only fail if they have sharp edges sticking out.

To the question in hand if you can't weld your stuck, needs a plate seem welded all the way round over the failing corrosion.
