This is a long process, but is successfully coming to a close, with the truck door hoisted up with the ladder because the lift support arms are off, and ready to soon be replaced when they arrive in the mail.
Before I remove the cover of the trunk door.
After I remove the cover, to get a better look of the inside and to determine the rust areas and how to fix everything, plus to see how I will have to replace light bulbs or alter the lights in any way.
Looking through the eye of the rust hole, from the damaged part under the lip of the trunk door, the bulb and plastic cover clearly shows (no pun intended) that water seeps through the gaps here and builds up (doesn't drain) and is what caused the rust.
Please don't tell me this was a bad idea, but I will have to find out. I got a can of Great Stuff to fill the gaps of the trunk lid, to shed water and will act as a noise damper.
Sprayed the foam in the gaps of the trunk door, of course following the rules on the can.
See the foam quickly begin to expand in the gap, which is its main purpose.
Day later, the foam was done, and it was definitely trial and error, because it expanded over the lock, and was unable to unlock, so I had to sever the foam away from the lock.
The trunk opens and closes successfully, but here is one opening I never want open again, behind the liner of the trunk and speaker, is what I thought was drugs when I started this project, is what I learned it was all along, a plastic covered sponge to absorb water, or keep water out.
Seen here is the power antenna assembly, foam pad, and the hole I have to fix immediately.
I can fit my fist into it, with a glove on of course, or I would be a dead man.
Stay tuned for the rest of this repair.
