My local aluminum supplier was quoting me gauges....

They mentioned 26 gauge for the thickest option and i was trying to get as close to .040 as possible. Anyone with experience in this area that could let me know a gauge equivalent to .040?
laying my hands on some colored aluminum is much more difficult than i thought and some suppliers have quoted me around $450 to get it to my doorstep her in Jackson, MS.
