Johnson's Well-Bake Core Baking Flux is a strong halide type baking flux for hard to bake radiator cores and for where baking applications where a vigorous flux is required. This flux contains zinc chloride to extend its active temperature range, yet it leaves little or no corrosive residue behind on the surface of the core after baking, when properly diluted.

      This organide flux is highly concentrated and should be diluted from 9:1 to 10:1 parts clean water to flux. Well bake is excellent for baking many types of radiators, including cores with steel fins or where one or more conditions are less than ideal.
