How exactly do you apply decals without leaving the really obvious film around the edge, also how should they bbe fixed to the surface without easily rubbing off.
This is a link to a wargaming site but it's a good primer on how to do decals. One thing the author doesn't mention is that to really make the decals disappear, use a gloss coat first. It gives the decal a flat shiny surface to stick to. If the finish is matte, tiny microscopic airbubbles will be trapped under the decal which cause silvering. Also be careful with the Solvaset solution he mentions. It is a form of acid. It won't burn you (at least I've never had a problem) but some decals don't react well. They shrivel and are unusable. It's always a good idea to test it first on a decal you don't need, unless you know the company.
