I know this subject has been discussed many times but I just can't get it right yet. I was using Dermagrip glue and the old silk span without many issues but struggle with the new stuff. I'm still using Dermagrip with lens paper and coffee filters which seems to soak up the glue better than today's silk span. I've let my mounts dry for months, sprayed 3 layers of lacquer gloss on first, and still they dry wavy! I'm open to all suggestions, changing glues, materials, methods, whatever I need to try.
