[TheForge] Rust Finish

[Woolley]

Greetings,

Just wondering what everyone is using for a quick rust finish on steel.  I pickled mill scale off of some tube steel yesterday with muriatic acid then sprayed some hydrogen peroxide for an orange, thin rust then clear coated to fix.  I'd like to acheive a darker finish quickly without buying commercially available mixes like Jax or Sur Fin products.  Is anyone using chemicals for a rust finish that are readily available?  Thanks.

Regards,
