Fender repair?

Both of my lower rear quarters were rusted out. Had to cut about 6 inches up from the bottoms. Just a little up into the wheel arch. Left the bottom channel for reference of the contour. Used sheet metal from old appiances being scrapped. Exact same guage. Got a cheap flux welder for $89 on Amazon. After some practice still made a mess of the welds. Took a grinder to it to smooth it out. Still wasnt perfect skimmed a light layer of bondo on it. Sanded primered and rattle canned it. Turned out awesome!!
