Great job capturing the look of your inspiration.
That's funny, I also had my instagram account canceled with no explanation, even after contacting them. I think they don't want old people to be on there.
I also use liquid glues such as Bondene or Tamiya. I use styrene strips on the backside to aid alignment and to reinforce the joint. Take extra care with your cuts and make the seam fit as well as possible to provide the best possible glue surface. Use small pieces of styrene to fill any gaps. I also use sprue-goo in any remaining gaps or holes.
There are a lot of different putties available so, if you've had trouble sanding some, try a different putty that may be easier for you to work. A good product to use on a small divot such as yours is "sprue goo", liquid plastic cement mixed with small bits of chopped up plastic sprue. Being of the same material as your model body it will sand and finish the same once dry. Make sure you use sandpaper backed by a hard material so that you don't sand a bigger deppression into the roof.
Thanks. It was very easy (and cheap). Everything except the wood beams was printed from images found using Google Image Search. Some very basic enlarging and cropping was done with MS Photo or Paint. Pics were spray glued to foam core board.
Not exactly a "diorama" but I used internet images printed on standard computer paper to create a backdrop in my display case. The method works especially well for scale posters, calendars, signs, window backgrounds, etc.
I used 3D Louver decals by Archer Surface Details from Teds Modeling and was very happy with the results. Very simple installation and no body work required.
The "Iron Butterfly" title caught my attention 'cuz I like that band. I also happen to like Viet Nam era gun trucks so I really enjoy your model. Looks great and I'm sure it will look even better weathered.
Thanks for the nice comments. Looking forward to seeing what someone else does with a Tbird kit.
Here are a couple of W.I.P. pics to show some of the changes I made to this kit. Cut out the molded-in seat and added driveshaft tunnel and floor; used old airplane horizontal stabilizer as fairing/rudder; cut molded in exhaust.
