Arrange your hairpin legs on a protected work surface.
Use a foam brush to apply Liquin oil paint coating on the newly-cleaned legs. Coat all surfaces and allow to dry for 24 hours.
Attach the legs to the table using #10 panhead lag screws and the holes you drilled earlier.
Whoo-hoo, it's almost a table! Carefully flip it right side up and look at it, isn't it pretty? But don't put anything on it. Especially not beverages. Any stains the wood gets now could be emphasized by the epoxy finish. Cover the table with plastic if you can't epoxy it right away.
