MM, I don't know if you can get KMER any more. pc&e carries KTFR which does the same thing. The pre bake, post bake, and developing times are a little different. I found that KTFR was a bit pricey. It was about $200 dallors. You can get a real deep etch using KTFR. I use a laser printer with clear transparency film to make the stencils. Good luck--ray--
