Using the 'old school' approach, this is one of the simplest and best ways to apply metal flake to any surface. Just spray your desired colour of basecoat, then a layer of clear coat laquer and when the clear is still wet, dry spray the metal flake over the wet clear coat. The flakes will stick to the wet clear coat and any excess will fall off.

Once you have the desired coverage of flakes, bury them in clear coat till your project is nice and smooth. To add a professional finish, sand your project down with 1000 grit paper and then add one final coat of clear to seal your project.

Tip: Keep your work area clean, so you can re-use the flakes that fall off - again and again. This will save you waste and some cash in the process. To make it even easier to catch the unused flake, place some paper on the floor or spray in a large cardboard box.
