Inside Frame Treatment - RUST
Hi Guys,
I've got my 64 down the the bare frame and have spent a considerable amount of time and money restoring the frame metal and replacing the entire upper-forward birdcage right town to the pillar caps (that was NOT fun).
I used the Internet to look for a way to both remove or convert the remaining surface rust on the inside of the frame and birdcage and protect it from future harm. There seemed to be two problems: First, you need to get into inaccesable areas and second, you need to remove the rust and make sure it doesn't come back. Lots of people had the question(s) and there were lots of different solutions but nothing jumped out as being the "best" way.
Here's another solution:
The only company that seemed to provide a single solution is kbs-coatings. They provided both the three-step chemical process http://www.kbs-coatings.com/KBS-Fram...it_p_8-26.html and an applicator http://www.kbs-coatings.com/Undersea...e_p_10-37.html that is perfect for both the frame and birdcage.
Here were the steps:
We finished and perfected the metal.
I spent about an hour (in the evening) spraying all of the inside surfaces with Aqua Clean. Let it sit about 2 hours (it didn't dry, it's humid here in socal at 5pm). Then used the same applicator filled with water to remove the cleaner.
I let it dry during the day.
Next night, I spent about an hour spraying all of the inside surfaces with Rust Blast (converter). Let it sit about 2 hours then used the same applicator filled with water to remove the Rust Converter. Some of the visible surfaces turned a patchy gray/white.
I let it dry 2 days.
Last night, I taped-up all of the holes except the ones I would use for application and spryed a 50/50 Rust-Seal + Thinner mix into the inside of the frame and birdcage.
I let it dry 2 days.
To add the correct color, I lightly oversprayed the birdcage with Green Zinc Chromate.
While this might not be what GM did in 1964, it seems reasonable to do what we can to minimize rust damage in the future.
Just wanted to share :-)
