PST HP100 Internal Rust

[Peter_C]

Thanks for the info. I assume the cylinder brush is the same as the whips I have heard about? Similar to a few posts down from yours?

Thanks again.

Yes they are the same thing.

I have read where many prefer to use acid over tumbling to clean the rust out, but I really do not want to keep 5 gallon buckets of acid around, nor do I want to have to dispose of the remnants. (Although my gal is a chemist and I could ask her to do it!)
