Preview of the tools that I used to build this model kit. Note: I didn't bought all of them in 1 shot. My advise is to only get the tools that you need as you go through the kit building.
Cutters (cut out the plastic parts from the runner), Gundam markers, cotton buds (apply decal, wiping excess ink during panel lining & apply oil to moving parts - very useful tool), craft knife (for cutting decal), toothpick (for aligning decal), screwdriver (for the model stand).
Brushes for painting & applying top coat.
Gundam markers for coloring the pilot & cockpit.
Cement (for joining the hand grip), paint remover for removing excess ink during panel lining, mark softer (applied on top of decal - use this most of the time), mark setter (applied on model surface prior to decal application - seldom use), mild retarder (slow down the paint drying - seldom use).
