CaswellPENETRATING SEALER 1QT

Follow the instructions

Worked as it should

No issues. Rinse parts well BEFORE putting oil. Put parts in wet then stir/shake.

No instructions included. Not much info even on web site. Product is very watery. Prepped steel surface and applied "sealer" in side and out. Allowed to dry completely. Did not change the appearance of the metal at all. Have no idea about seal but we will see with some use.

I'm new to machining and the cold bluing process, I made a part for my old Bridgeport and blued it instead of painting. The part looks great. Time will tell if it stays that way.
