The game will soon be getting its first models on sprues
My number one tip is to not cheap out on tools!
specifically your nippers.
I highly recommend
Wave Materials Ht389 HG Fine Nipper for Gate Cut.
They cut like the fancy god hand nippers but are way cheaper. It’s like $20.
These things are worlds better then the typical flush cutters. They cut right at the gate and leave a flush serface that requires almost no finishing work.
But they are delicate and should only be used for thin gate cuts don’t chop thick hard sprues with them.
If the new kits are styrene there are even more techniques you can use for quicker removal of flashing and mould lines.
Harder plastics are very receptive to mould line removal just by scraping with a hobby knife.
Plastic glues will allow you to weld parts together so there are no gaps to fill!
