Metal patch/hole fill, repair materials and techniques
My newbie build progresses!
So, I'm finally at a place where I'm preparing the exterior for it's first of many coats of paint. I'm cleaning all the sticky tape, and priming any rust spots, and doing my first light sanding. I have several spots, like the one in the attached photo, where things have either been removed, or, in some cases, where I've made holes in the process of mounting things, which I then moved. My question is, what process/materials should I use to prepare these areas for painting? For a 2 - 3 inch hole, I assume some bonding material is inadequate. Should I get some sheet metal and cut a patch, like pair of jeans? If so, how should I attach it?
As always, all suggestions appreciated.
