flat clear comes in many varieties. It's basically a clear
colored paint but with a dull finish (so that it's not glossy).
There are a few varieties, mainly Tamiya, Topcoat or Mr.
Hobby.
Then there's the difference of type of paint (lacquer (quite
poisonous - spray only in an open area) or acrylic (not as
poisonous - but still spray in an open area).
The choice of which one to use depends on what type of paint
you're painting your models. The solvent used in lacquer
paints will dissolve acrylics. So if you painted using
acrylics, DO NOT spray a lacquer clear coat - otherwise your model
will turn into a runny/melted mess. However, if you painted
using lacquer paints, both lacquer and acrylics work.
alcoholfueled-vii, if I'm using Gundam markers, will lacquer
clear coat dissolve anything? Shouldn't be as Gundam markers are
alcohol-based... ?
