Frequently asked
Does a brush-on blackener protect against corrosion on its own?
Blackened finishes usually need a follow-up oil or sealer to resist corrosion. The data sheet says what to apply after blackening.
Does the surface need preparing first?
Yes. Blackening solutions need clean, grease-free metal to react evenly. The data sheet gives the cleaning steps.
