BIRCHWOOD CASEY's DriTouch Amber blocks rust and corrosion on all metals without affecting part operation. The colorless, odorless barrier film is highly resistant to humidity and will not drain off parts or wick off into the packaging material. The film also has a flexible, self-healing property, to re-flow and re-coat areas that are scratched or damaged during handling. May be applied by dipping, brushing, or low-pressure spraying. www.birchwoodcasey.com
