bulkhead qs

when i paint me 90 i have a small repair to do on the front bulkhead..

its the usual problem when the wind catches the door and throws it open and it creases the side of the bulkhead,
what is the best way to repair this crease,is it just a case of filler and rust proofing it,

whats the best way to repair this problem..i have access to a welder if needed...ta

as you wish, filler or lead if old school

Lead is the proper way to do it but it takes patience and a modicum of skill.
Not too much heat but just enough to get it to melt and stick.
Shape it as for filler then undercoat and paint.
Dont forget that lead is poisonous especially the fumes when heated.
