Just before summer holiday I purchased this kit on sale at "my" hobby store and I planned to take it with me and paint some in the evenings at a summerhouse. I managed to give it a coat of white and to start with the rust before the departure, but didn't take it with me in the end. I picked it up recently because I had an idea for the chrome strip in the windscreen seal, and simply finished it.
The kit is close to perfect as is, and there is not much I had to add. I used Highlight Model Studio photeteched sets for the wheelweights, and for the wipers (though I modlified the latter, and am still not sure if I'd rather have them scratchbuild as I usually do), I added the wooden lining on the bed, made the keyholes in doors and the fueldoor a set of numberplates (Hasegawa doesn't add numbers to their decal sheets), a telescopic antenna (works) and I ended up painting the word NISSAN freehand on a piece of white decal, and then transfered it on the truck letter by letter.
As for unusual techniques, I opted for not painting plastic bits that are plastic in real life too, like the bumper ends, the grille, dashboard and some other bits on the inside.
The kit is very easy, and besides the headlight glass where I wasn't sure how to attach it, and the hubcaps that had to be masked, whereas in Hasegawa's Honda these are separate bits that are way cleaner to attach, there were no issues at all. I highly recommend it if you feel like building out of box sometimes.
