Hi John, 

I saw that listing and didn't realize it wasn't for the entire box (which I really wouldn't want to buy). It's definitely less expensive than McMaster for this. Maybe I can talk the seller into throwing in one of the lockwashers. 

I'm going to have to try the Rust-Oleum stripper. I think I've seen it before and it's supposed to be good. 

Thanks for the pointers!
