Cerakote film thickness ?
Cerakote recommends an optimal coating thickness of 0.5 to 1.0 mil if I remember correctly (.0005" - .001").
Half a thousandth is pretty thin to say the least. Do you know what the product is by chance ? Is it a true surface coating or some conversion coating or plating process because the film thicknesses you are referencing, and I believe you, are so unbelievable thin for an coating like polymers or similar that I can't hardly imagine the control process. Very interesting for sure
My response may be in error now that I look at your post. Are you saying
0.5" or .0005" ?
