Overall sequence for decaling

There is no absolute order.  For instance, some folks use a gloss version of camouflage colors, eliminating the first clear step.    Some people only use a single flat coat, weathering over that. I frequently put on the canopy much earlier, and mask the transparent parts, so the painted or metallic parts get weathered, dulled, etc.  I have also occasionly weathered the transparent surfaces if it is to be a heavily weathered model.  Also, to weather decals, I have also put a very light coat of the base color over the applied decals (hard to do on tricky camouflage but easy, for instance, on contemporary navy jets).

You have the basic sequence right, but it is not a hard and fast sequence, so if there are things that cause you to alter the sequence, that may work too.  Be flexible.

Sounds good to me.  But I prefer Testor's laquer Gloss Coat instead of Future.  If your color coat is acrylic, I think Testor's lacquer gloss coat would work better.  Future would tend to interact and soften the acrylic color coats, and maybe cause runs between colors.  Then, when all is finished, use a light coat of Testor's Dull Coat, or semi-gloss lacquer, according to your preferences.
