First Truck Build

The Tamiya putty is good for fine filler(like scratches, etc...) but you need bondo to fill the gap of the cut. I used "Evercoat" #100416 metal coat. (Ebay) A lot of people on the forum recommend this. I did the same thing with the back cover. For gluing the pieces and backers together use Tamiya glue (orange) or Plastistrut glue, works pretty well and welds the pieces together. Also fill in the gap as much as possible with bits of plastic possibly styrene and glue before bondo fill, gives a stronger joint and less possible crackage. There are right ups on this if you run a search on forum.
Hope this helps.
