we never had luck with the web tack... we print tons of hoodies, primarily black or dark that would need an underbase. the web tack always turned to goo and stuck on the inside of the garment, or left residue on the inside of the garment.
we spray camie 375 - i usually buy 60 cans per month in the summer and 144 per month in the winter. if there is a better way, we havent found it. got to balance time on press vs the cost to clean up after...
