Rust 911 before and after

[zzlegend]

About 28 years ago, I had my 57 olds hood louvered. 2 guys did a great job. Brought it home and installed it and then life got in the way. Fast forward to last week after 28 years, and started working on the olds. Opened the hood and kicked my butt for not priming that hood back when. So I removed it and I taped a plastic sheet over the top of the louvers and flipped the hood upside down. I bought some rust 911 and mixed about ten gallons using their formula and poured it in and made a lake with it. After about 1 to 2 days that hood looked like brand new sheet metal. I drained it, rinsed it clean, used wax remover and sealed it with epoxy primer. I should have taken a picture after it was clean. My bad..
I was going to sandblast it but was worried about warpage with so many louvers. Just my 2 cents.
