Have never tried to save & re use a can of foam before but............didn't use much so I blew out tube at end of day folded over & placed onto stub on trigger.Next day just didn't seem to be coming out right...........& pop-blew the trigger/straw right off from pressure. I had about 100 blobs the size of a tick(empty to fully engorged)from my shoes to my neck. What do you do ? I tried not to move much till it set up enough, but was right in the middle of setting a waterfall stone mid stream. I had shorts on & the worst spot was right at the bottom of my shorts/thighs. Most virgin blobs came right off-with a few hairs. I just cleaned up what I could soap & water in shower. Hand cream applied before bed. Nice warm shower next morning & scrapes right off with your fingernails(go with the grain of your fingerprints)............................Lesson Learned.
