Is there some kind of guide or order to applying paints

That is correct, a "dull coat" is a cleat flat (matt) finish.

I will add another consideration. When applying your main colour coats, if you are applying a multi-colour camoo scheme, the general rule of thumb is to apply the lighter colour first and then darker colours over it. This prevents "show through" (unless you have some reason to allow it) as it's much easier to cover a light colour with a dark colour than it is to do the reverse.

Thanks for the replys as im from OZ do you use  Future or Pledge one go

I've tried Pledge One Go and while it works nicely for dipping clear parts, I don't like the finish when used as  a gloss coat.

My personal preference is not to use a gloss coat at all in preparation for weathering, but where I do use one, I use Tamiya X-22 clear acrylic.
