An aqueous liquid composition containing polyethylene glycol with a molecula r weight in the range of about 200 to about 8000, nonionic surfactant, and a corrosion inhibitor, and optionally, amphoteric surfactants and fluorinated surfactants is useful as a highlighting liquid for detection of surface irregularities on shaped metal surfaces and for preventing adhesion of weld splatter on surfaces coated with the composition. Preferably the corrosion inhibitor includes alkali metal salts of boric acid and of a mixture of branched chain carboxylic acids and amino acids.
