well dont hold can in one place, use primer first and let it all dry properly before you put color on to it and the same for the laquer.

as said dont hold can in one place, spray from about 10-15 cm away in sweeping smooth motions left to right. fully cover with a coat of primer let it dry for a good 6 hours then you need to use really fine wet and dry and give the paint a key for the next coat. then use color, let it dry, give it a key then laquer. you can buff down the laquer to give it a nicer shine after too.
