Hi, i'v just brought a Defender 90, 1988. it has a few rust issues. the main one im concerned and want to fix is just bellow the front air vent flaps at the front. i think im going to either A. remove the section and weld in a new one or B weld a patch repair to it. im looking for any advice you all could give me as im such a novice but reall want to bring my Landy up to scratch. thanks for reading.
