I bought this jus' recently from my LHS cheaply, and as a bonus the kit comes with two figures!
The plates runnin' alongside the hull are already moulded onto the hull, and Dragon have supplied a 'correction sheet' and a seperate sprue of PE containin' two long strips that run down the edges of the fender plates, along with some very tiny bolt details.
After fittin' these parts, they came up a little too short so I cut to size some pieces of very thin styrene sheet, and added them to the areas that needed attention. I'll fill the small join with some liquid putty, although I reckon paint would be better 'cos there is no gap. Jus' need to make it look like it grew there, is all!
The turret went together well but the top plate did need a lot of sandin' underneath to make it fit flush, and not look like its raised and jus' hoverin' there. The weld seams are beautiful, and all the joins have been filled with liquid putty applied with a very thin brush and a steady hand. As a result there was no need to sand it back, the putty jus' becomes a part of the weld line.
