Body Filler Help!

Sorry mate. It's an arc welder with crappy sticks and in a hurry as well(again ). (excuse excuse)
MIG welding is bit too much trouble atm with too much wire brushing & no bottle atm.
I reckon your advice to use TIG later to smooth it out is a good idea, but that means lot of wirebrushing and cleaning as well.

I'll see how it comes.

BTW, the metal I used are scrap ones with odd sizes that hangs around the backyard.

If the welds haven't been painted over yet no need for wire brush just crank the Tig up and away you go , but you need gas for a Tig as well .
Other option is oxy acetylene if you can borrow or have a set .
