Spoke to Benjamin Moore specialist and he *recommended a water based primer
, rather than oil based. Says WB is more flexible, hence there should be
less cracking and flaking. I wasn't aware WB was more flexible, that way.

If you decide to trim the damaged portion, attach a board below the cut lin

And wear eye protection!!! Awkward position and sawdust flying, the debris
will definitely fly in your face.
