We did try ink then lipstick on the lips of recessed fan and can but it didn't work at all for the fan since the heat duct drops a little lower than the lips so the lipstick never did touch the drywall. The can did not in fact have a lip as my husband told me so there wasn't much of a surface to put lipstick on. It sort of made some marks but all in all it didn't work well for our situation. We decided to buy a Roto Zip and boy is that thing slick and made the job go so much smoother. We are doing a small bathroom with all sorts of issues so getting the dry wall in place is a bit of a circus act so avoiding the whole step of putting lipstick on the drywall surface and then taking it down again to cut out was a lot of extra work.
Thanks to all who responded.
