Hi All
When seating in my beams I mixed West System with microsphere blend and a little glue additive as well. The beams where they would contact the mix were covered neatly with brown package tape and coated with a polymer car polish as well.
The tape covered the beam holes and left a small ring showing when the beams were popped out, so I could drill the holes either while the beams were on or off, which was handy for the inside rear beam holes, because the bolt doesn't go all the way through the beam.
It only took a light tap out with a rubber mallet and left a very neat and clean beam pad <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" />
