Has anyone found a durable, indelible inspection stamp ink? We have an extreme case of smearing/obliteration because we have the boards dip coated (Humiseal 1B73). The manufacturer of our stamps is zero help, i.e., the best I could get out of them

I figured it was just going to take a little searching to find a (more expensive) stamp that used an (more expensive) indelible ink. Not the case. Just can't find anything at all, and the stamp manufacturers say not to use any ink but what they provi

We are looking at switching to UV cure for faster throughput. Does anyone know of any cost effective coating manufacturers? The pricing we are getting back are around $250.00 a gallon in 5 gal pails. This is more than twice what we pay for our curren
