After dry brushing with oils and Tamiya enamels, do we apply a flat coat on top? Will that negate the drybrushed effects? I have forgotten to soak away the linseed oil on cardboard, so it's a bit glOssy

Give it a few days to ensure that the oil (linseed or sunflower) has dried completely, then flat coat. I use Testors Flat Laquer.

The clear flat shouldn't eliminate the dry-brushing effects.

However, if the oil isn't completely dry, it can negate the flat coat and cause some semi-gloss spots to reappear. But no worries if that happens; just flat coat again.

Don't sweat the "cardboard" thing with the oils. All you need to do is allow a little more drying time.

Good luck,

You can put a coat of matt varnish on it, or a coat of satin varnish, whatever you prefer, or you can do a 50/50 mix which should leave an egg shell kind of satin finish, depends on what you prefer, some things look good left with a satin finish.

The dry brushing is to add highlights to edges and raised detail, so putting varnish on top should not effect that, sometimes the varnish will darken the effect, but that is normally a good thing, helps to take the "stark" finish out of it, blends everything in.

I would certainly seal the dry brushing with a good coat of flat clear. My personal choice is Testors Dullcoat, which is lacquer bases. Dries fast, and dries flat. However, as others have said, you need to make sure that the oil paint had dried.Sealing with clear flat won't negate the dry brushing, just blends it in a tad.

As far as dry brushing goes, I use both both Model Master enamels and acrylics. I don't like to use oil paint as they take a longer time to completely dry.
