Started out quite well but as the build went on it became apparent that it wasn't going to enjoyable. First things first; if you want to build one then replace the following; canopy, that is a must with all of it's silly joins. It probably could have been moulded as per the aftermarket one but seems like a 'ha'peth o' tar' to me. Exhausts unless you don't mind trying to hollow out grooves in the bottom, seats, resin ones are available or if you want to keep the kit ones than grind the moulded on belt off and replace with aftermarket. Instrument panel replacements are available as well. The carb intakes on the engine need hollowing out and a mesh frontage applied. The decals were atrocious and out of register, the ones which didn't break up in water silvered badly despite a gloss surface for them. Also, once you have the fuselage closed up then make sure it is absolutely spot on and lined up especially around the underside otherwise the fitting of the wings and struts will come back to haunt you. You could make a really nice kit if you spend a lot more on aftermarket than you do on the kit.
I left the underside metallic as I really couldn't be monked with the thing anymore. You may notice the paint run on the starboard side of the main float. That was just the last straw, well that and I'd found I measured the white disc mask wrong for the Swastikas kindly supplied by @Grunhertz
