Looking for advice. Want to build a Duster to run on a budget.

You totally missed it. I got banned for pointing out that a mod misinterpreted what a member said. Another mod said he didn't and I said it was right there to see, which it was. Where the mod was wrong got deleted and the discussion got labeled as an arguement by the mod and I got 30 days.
I was in the thread, I know exactly what happened. Clearly you haven’t learned from that experience either.
You are not helpful to a segment of the hobby that are doing things that you would not do. People in different situations and different wants . Don't tell me what I need to learn. I know all about what some people consider the right way and I've done it.

No person that knows a single thing about bodywork or metal repair considers what you’ve done the right way. You have no idea what you’re doing, and you have a lot to learn if you want to legitimately repair these cars. If you’re unwilling to learn, you shouldn’t be working on these cars.

Show me ONE source, a professional source (not YouTube!) that describes automotive metal repair using fiberglass, galvanized hardware store wire mesh, and 1/4” thick bondo as the right way to repair rusty bodywork. Books, manuals, product instructions, that sort of thing. From the current century. Thanks.
Regarless of what you think about what I bring here, there is no excuse for your constant exaggerations and attacks on my character. I'll no longer defend myself and will let you have it.

Yeah, too late for you to take the high road. I’ve got all your posts and comments, “constant exaggerations and attacks” describes your response every time I said your method of “repair” was doing more harm than good. And that’s a simple fact for anyone that knows anything about bodywork.
