Paint Picker is now Hobby Supermarket. Same site, same prices, same shops.
A varnish is the last thing that touches a finished model and the only one whose job is to still be there in a year. It is not a colour and it is not judged like one: the buying question is sheen and delivery, not hue. Matt kills the plastic shine that makes a good paint job photograph badly; gloss protects hardest and is what goes under a transfer or over a gemstone; satin is the compromise most armies actually want. Brush-on gives you control on a single model, an aerosol covers a unit in one pass and cannot be posted to every country.
Two coats of matt over everything is the default that goes wrong least - and the commonest failure is not the product but the conditions: varnish sprayed in cold or damp air goes cloudy, and no brand is immune to it. Gloss first and matt over the top is the durable combination if the model will be handled. Buy the sheen you want; the price spread across brands is small next to the cost of stripping a frosted army.
