Thanks Brenda and Paul.
Brenda, I use house hold acrylics. Flat and if not available satin. If you get the sample pots they are good value.
Once I have painted the colour, I spray a clear gloss lacquer x 2 coats over it all.
I use a soft brush and just lay the paint on any old how, then brush it out lightly in the one direction. When dry, cut back with 220 or 360g paper and re-coat.
Yellow, Oranges and Reds are pains, in that order for covering and some times 3 coats are required. By cutting back between all coats, including the clear, you tend to knock of any outstanding brush marks and imperfections.
