Sand and Fill Fiberglass

  This evening I used my finish sander with 100 grit paper to sand the filler I applied yesterday.  I sanded the whole surface to prep for additional filler.  I also used the small sanding drum on my Dremel tool to clean-up the pivot bolt holes.

 From the camera angle it looks like the bolt and washer could not fit, but actually they fit into the hole really well.  I will need to do some additional work on the left side hole.  I mixed some more resin with black colorant and micro-balloons and spread a new layer of material over the fiberglass.  I think I can have the low spots filled with one more application of filler material.
