you dont NEED a air compressor and spray gun for a good finish this was done with cans http://i141.photobucket.com/albums/r71/stu_m_photos/th_2012-12-14085345.jpg It is all about the preparation you would need to thin it down with the correct thinners for the paint If you have enough paint you could try this paint it on something with a brush and sand it down with wet and dry once it has dried properly to get all the brush marks out use a really fine wet and dry though start with about 800 grit and get finer finish with 1600 once its nice and flat with no brush marks get a tin of lacquer/clear coat halfords one is ok not the best and its cheap...then give it 2 or 3 coats and see how it comes out If you prep it right and sand it really flat it might turn out OK the lacquer/clear will give it its shine back dont worry about it been sanded try it you never know it may work it may not but you have the paint now so you have to do something with it all spraying does is put a nice even thin coat on with no brush marks
