Drained and repaired the spare wheel well today.
This here is a drain plug, you can see a little of the gasket material on the right side of the circle
With a little persuasion the plug came out and drained all the water to the ground. I left the trunk to dry over night. Then started sanding down the rust and bubbled paint.
You can see the drain hole a bit more pronounced now that I've removed a few layers of rust.
Almost there. I also used a brass brush to loosen any other rust not easily accessed by sand paper.
After a final pass with some 120 sand paper I applied a layer of rust stopping primer. I used gray because this is just the spare tire well and isnt going to seen frequently.
I also cleaned and applied paint to the other side of the plug to prevent it from spreading beneath the undercoat. I have now popped a 1 inch body plug into the drain hole.
TOMORROWS PROJECT: removal of rear bumper and sealing the body from future leaks.
Here's where the water is coming in, note how the fabric pad for the wheel chock is soaked. During this project I have discovered that the vehicle has been in an unreported accident. There is impact folding on the spare wheel well on the same side as the leak. It doesn't seem too damaged and could probably just be adjusted and sealed. It looks like someone backed into something or scrubbed a guard rail trying to drift it.
