How much “finish” work is required on the composite parts like wingtips, etc., that already have a “finish” on them?  Do they still need pinhole work or are they pretty decent?

It's a matter of preference, the wing tips and emp tips are gel coated 

and most of the pinholes are filled. However if you hold them up to the 

light you can see the weave pattern of the fiberglass cloth through the 

gel coat. Additionally, many of the tips are not 'perfect matches' with 

their aluminum mating parts and will require 'finish' work to get them 

faired to the same level.



And the Cabin Cover...... Well that's a Phd project in 'finishing'.

TDT - where you been hiding????

All of the gel-coated parts have a little bit of an uneven surface as if the coat shrunk a little in the checkerboard pattern of the glass cloth.  Using filler primer usually takes care of most of this, especially if you spray a couple coats and sand it between coats.
