LOL! The "b" and the "w" are not even close to each other for that simple misspell. I misspell also but that one is too easy brown, you gotta get as much out or off as possible then coat it with por15 or rust bullet. I have also heard that there is a neutralizer you can use, but can't think of the name.
Napa sells a rust neutralizer called "Rust Ban" it workes very well. Also Eastwood company sells a 2 part rust neutralizer that workes very well(they have it in aerosol form too). I have used both on many projects and have yet to see rust re-form where the stuff was applied.
I tried to use the kitty hair. But, I think my problem was the kitty was still attached. Yep, neutralizer from Napa.
