Clear Coat Necessary?

[Callandor]

I am finishing up a model with no decals and the paint already has the desired finish (flat). Is a clear coat even necessary? Some of the paint is white. Would clear coat help prevent discoloration?

you don't really need it - but the clear coat can make the finish more durable. If you're not doing panel washes or anything like that you don't need the gloss. If you're not going to be handling it a lot, you don't need the overcoat.
