BIRCHWOOD CASEY's DRI TOUCH Amber blocks rust and corrosion on all metals without affecting part operations. The colorless, odorless barrier film is dry to the touch and highly resistant to humidity and corrosion. Thin enough to rapidly penetrate recessed areas and displace moisture out of the part, it is flexible and self-healing and will re-flow and re-coat areas that are scratched or damaged during handling. www.birchwoodcasey.com
