|Rust Close Up|
|1st application of Ospho|
|Close up white residue|
I'm now wondering if the beams were covered with something besides scratched paint that didn't react as I expected with the Ospho. Anyway, if you have any ideas on how to proceed, please let me know. I really don't want to spend another 6 hours tomorrow sanding and re-applying the Ospho, but I don't want to paint over the rust either.
