Nice work

I have seen cardboard as backer for bondo on rusty trucks seen a bronco where the fellow rivited the patch panels over the rust spots

My aim will be after i get a mig to make my work look close to yours
Practice will help

I seen a trick one fellow showed me make the patch and the panel trimmed close to same size tack the two together use zip disk cut at a 45 degree angle back tack the fresh cut flush make the next cut and continue until you have the patch completely flush fit finish welding and watch how much heat you drive into the panel
