I just finished my T28. I have come to the conclusion I hate the following:
Bogies
Individual guide horns
OD paint
and kits made up of sprues from half a dozen other kits.
There is a lot of left overs on this kit. As to the guide horns, I used a curved blade scalpel and just ran down the line cutting them off the sprue. Then I poured some tamiya glue in a small shot glass. I brushed it on the track about 5-6 at a time, then picked up the guide horn, touched it to the glue in the glass, then put them on the tracks. Took about 2 hours for all 8 track sections. However, if you plan on putting the outer tracks in place permanently...you really only need horns on the bottom. The top will never be seen.
Another thing, dont glue the "mounts" for the outer tracks onto the main hull/fenders until the outer tracks are taped in place. And for the hull mounts, you will need to cut the tab off of the bottom. If not, it locates it just over the edge, causing a horrible gap with the outer tracks.
