Hehe.
I thought the "Finish model" would be last!
Seriously. I´d add a coat of future also before decals. They attach better and there will be less decal silvering.
After washes I would add drybrushing to bring up the details.
Also, you might want to apply a flat coat before weathering effects alike mud or dust.
I assume you make land-based vehicles?
1) Finish model. (Well, for this me)
2) Paint model.
3) Clearcoat
4) Apply decals
5) Paint clearcoat (future)
6) Apply wash
7) Drybrushing
8) Matt coat
9) Weathering
10) Sit back and enjoy my first time masterpiece???
