Well I didn't get as much done as I had hoped to, but I did manage to cut and trim the Canopy and get it tinted black and mounted to the frame work.
as far as the interior goes in the canopy frame I just went with grey paint.

Heres what I did ,I started out by laying up the pieces that make up the frame work on top the wing and in there respective places. I needed to trim a little and sand some to achive the fit I wanted.After I had things fitting I laid a sheet of waxed paper under it clamped the ends in place where it will later bolt on.
My dowel hole was off just a tad , but by turning the front pieces of the frame work I found the hole had not been drilled on center.
After lineing things up good I glued it all together, a little bit of a gap under the stringers are not going to hurt , however I did need to sand a relief in the rear part to clear the wing and allow the stringer to set down in place.
I then added the interior piece and glued it. This takes a little trimming to get it just right.
Also glue the backrest in place so it stands up W/O any help when removed.
I cut and trimed the canopy while this was drying , then decided to go ahead and tint it black.
The Canopy is plenty large I had alot to trim off even when it was cut on the given lines. But this may not always be the case so cut it over size to be on the safe side.

When the glue has set I took the clamp off from one side and drilled a hole to fit a 2-56 blind nut I then used a 2-56 screw and held that side together while I did the other side.
I then removed the frame and reglued anything that looked weak.
I then sit the canopy on top the frame work to check the fit, Be carefull here not to pull the headrest down or up.
Useing some small plastic clamps that won't mar the finish I clamped the canopy to the frame, doing just a little at a time I glued the canopy to the frame I used Med CA, Then reclamped that area untill dry.
After the whole thing was glued and all set I then trimmed the excess off the bottom and ends of the canopy to match the frame. I trial fit the canopy several times as I did this to make sure of a nice fit along the top of the wing saddle remember when I said a little gap was ok in the frame , well nows the time you take care of that gap with the canopy itself.
This takes a little time to do, once your satisified with the fit drill the holes thru the canopy from the holes you made in the frame work and try the screws. If you didn't push or pull the headrest the holes will line up ,mine was off a tad so I needed to enlarge the holes a little.
OK after I had it all glued, trimed and bolted in place , then it was time to paint it. I just used the exsisting lines on the canopy and some fine line tape for the edge of the paint line and masked it off then painted it useing some Automotive paint I had in a can. I don't prime it because if you do it will show on the inside.

I had forgot just how much of a PITA this part of the build is *LOL* Oh well its done now and we'll be doing some more later today.
