What are particularly bad areas for rust?
On the Vega, check the rear quarter panel drains. If clogged, the interior of the panel will stay wet and rust. Enlarge them if needed. Robert (twelve_second_vega) adds: “I see a lot of rust around the windshield and hatches on Vegas. I discovered that I can drill holes in the window channel area and let water drain into the cowling, preventing rust formation. The rear hatch’s glass channel can be drilled on early cars, but I am not sure about later models. Be sure to treat the drilled area before reassembly! With the windshield out of the car, you drill a hole into the bottom of the glass channel at each corner, about a 1/4” hole is good. This will open into the interior of the car. Next, from under the dash, drill another hole through the inner firewall and into the cowl cavity in front of the windshield. I then epoxied 2 nylon tubes into these holes that carry the water out of the channel and allows it to drain into the cowling. It may be overkill in one respect, but it keeps water
