Time to start glassing the form.  I probably do not need to do that for a one time use form but I am looking for some practice before taking on the rudder job.

'It doesn't have to be perfect, it just has to look good.'

Note:  Styrofoam melts a bit with Bondo.  Pour foam does fine.  I have now used 6 different materials filling the form before going to glass/epoxy covering.  These are: Pour Foam, can foam, styrofoam, spackle, drywall filler and Bondo.  Should have taken more time to setup alignment pins and back fill with spare wood blocks.  I ran out of pour foam but managed to empty my shelves of old materials from old projects.  Looking pretty good.  I think by next week I can prepare for a glassing.
