  • Clear chromate for zinc?

    I need a clear chromate for copycad&zinc plated parts.

    Caswell only offers yellow, OD and black.

    Anyone know of a source for small quantities of clear chromate? or know what chemicals it takes?

    Use the yellow chromate at a 1/4 of the minimum strength.

      At 1/4 dilution strength, how does the thickness and durability of the coating compare to regular strength?

      Or is it just a matter of leaving it soak 4 times longer?

      Does it still have a hint of yellow color, or completely clear?

      I'm trying to restore pieces that were originally done with a commercial blue tint chromate.

      Thanks!
