I've got a hatch with nice sharp edges, and I'm contemplating what will happen when I attempt to apply silkspan. I'm pretty sure that if I leave it knife-sharp as it is now, I'm going to have a mess when I try to apply silkspan around it.
What's the best way to handle this? If I knock the edges down a bit, how far should I go?
As a separate question, how much room should I allow for finish in the gap? Right now it's a pretty consistent 1/32" gap all around.
