Rust on Underside of Hood

[Driver_WT]

The hood on my 53 Chevy Truck needs some work on the top side, but not too bad. On the other hand, the underside of the hood is covered with rust, no holes but lots of surface rust. Can I sandblast the underside of the hood, or will that cause problems with the hood? I thought I had seen somewhere that someone had warped their hood by having it sandblasted?

The rust on the underside is too heavy to just sand off.

Thanks.
