As silly a product as it is, I'd gotten rather attached to Laser Dark (to darken wood engraving) but it seems kinda expensive for a can of spray paint and I'm interested in using colors as well. I've never had luck getting quality results using hardware store rattle cans, it's either too runny or drys with a skin that complicates mask removal.
I'm down to invest in an air brush if needed but I'm looking for a spray product with similar consistency.
