I was trying to decide between going the expensive route with BilgeKote or the cheap route with Killz for underneath the galley.  I ended up somewhere in between.  I found a can of white Brightsides in the barn left from a previous tenant and figured I would go with that.  It isn't as strong as doing it in BilgeKote, but it is a lot cheaper!  I put the first coat on today hoping it would do a good enough job covering that I could stop at just that one.  Sadly I don't think that is going to work.  I have off of work tomorrow, so hopefully it will be dry enough to put on a second coat.  The instructions say 16 hours, but it is pretty cold out there so I'll have to wait and see.
