Hi, ( sorry i have posted this topic twic now, but im not sure were it should go. )
How can i remove gloss vanish off plastic models without damaging the the paint work ?
I don't know if its possible to take off just the varnish and not the paint, but I think hitting it with some matte varnish might do the trick. Again, I'm not sure if that will work, but its what I would try.
Break fluid might work. Also I believe it is called Castrol Super Clean (again in the car aisle or automotive store). both are supposedly very effective and safe on plastic. I haven't used them but might be worth a shot.
I do believe both will dissolve glue so if you have a multipart figure you will need to re-glue. I have also heard it eats away green stuff.

So far as I know, any method that takes the gloss off will also take the underlying paint as well. You can try putting some matte varnish on top to counteract the gloss, but I wouldn't get my hopes up.
So, short answer : no, you'll probably have to repaint the whole thing.
Just spray dullcote on top of the gloss, it works fine!
You have to be very careful here using Brake Fluid or Castrol Super Clean, as it will strip off (completely as new) all the paints along with your layer of gloss varnish.
Your best bet would be just apply a thin layer (watered down, very thin layer) of matt varnish, and as usual, you have to be careful here too, because the way matt varnish works is that it "eats away" whatever (top layer of paint) it is applied on and creates a protective surface when it dries. That's why sometimes when you apply matt varnish on your beautifully painted model and it would ruin it. Remember to always water it down when you are using it! Too think of a layer of varnish will cover all the crevasses on your model and you dont want that to happen!
