Itinerant Air-Cooled

While the van is sitting in the garage waiting for new boots I thought that I would look into repair/painting the rust on hatch.



What I would like to do is push in the window and seal at this corner. I do not want to remove the entire glass. Is this possible? Or is there a better way?

If you can see rear hatch rust, there is probably 75% more that you can't see, under the seal.

This was 100% invisible:




This "perfect paint"……




…was actually completely lifting off due to rust and water incursion…




My recommendation is to acquire a new seal, remove the window, scrape the large chunks of rust out, wire brush the rest, and use a Rust-Catalyzing Primer on the remaining metal. After 24 hours, you can top coat this with a color close to your car. I have one spot on mine that I have to inspect every half a decade or so.

Here was 2012:




And 2016:




After treating with a wire brush, RCP, and a top coat of Rust-Oleum paint:




Here is my favorite catalyzing primer, available from O'Reilly's or Amazon:

You can spray it into the cap and use a watercolor brush to apply it locally. It converts the iron oxide (rust) to iron phosphate (or similar; inert) so you can treat it like a primer once it's dry.

Good luck, and let us know if you have any questions!
