Richard,
It will get everywhere when you spray too much on. It has a to 1
expansion rate. But it fills all voids.
A large sheet of plastic and masking tape will protect the rest of the coach. Yes it is difficult to trim but the rewards are worth it.
As for as the wiring goes I am an electrician and the the installation of a conduit before spraying, or anywhere else is important to me in my opinion, for future access.
It does not need to be e.m.t. or rigid conduit but the conduit that I use in my GMC is called "smurf" tube. It is blue of course, flexible,
and very, very light weight It connects together to make any length you desire.
Makes access very easy, And it's available at all home depots etc.
