Using foam in a can to fill gaps
Has anyone used the "canned" spray foam to fill in gaps around water lines that go into the trailer? Any issues I should be aware of? Thanks!

It's also not a good bet that you'll be able to store away a half-used can and get it to work afterwards. The stuff in the can is OK, but the trigger mechanism and tube are hard to clean sufficiently for another use. If you have a bunch of things to be foamed, get them all prep'd and then go around and spray them all.
The standard high expansion kind can sometimes expand beyond what you want, especially if confined in a tight place, and cause some things to buckle or warp. This is probably not a big problem with water lines, but can (for instance) be very troublesome when sealing around double-hung windows or doors in a house.
Particularly in an area exposed to light, it's not a bad plan to put some paint on top of the foam once it's fully cured as UV light breaks it down over time.
Paint or use spray rubber in a can to seal and protect the foam from breakdown.
