I use a white primer on my stockers, usually Krylon primer white, and when it has dried, I'll smooth it out by using 600 grit sandpaper. For the gloss white, I'll use a rattle can, give it a few days to dry out, and then follow with airbrushing the other colors. I've learned it's less expensive (both in time and money) and you can still get good results by using primary colors like white, black, and red, in spray cans rather than airbrushing. Hope this helps and good luck!

For light top colours always use a light undercoat (ie white) Even some darkish colours can also be affected by the colour of the undercoat, check this out with an old body or a plastic bottle or something. Do half in a dark undercoat (ie grey) and the rest in white undercoat then spray say a red or orange or medium blue and see the difference.

If you used a dark undercoat then lightly sand and overspray with a light (white) undercoat and then apply the top coat again. If you tend to spray only misting type coats then you'll have to do more coats, hence you should always try to use an undercoat similar in colour to the top coat.

As always try it and practise to get what is best for you. The above works for me.

It would depend on how thin you are putting the coats. I think I have seen someone suggest useing a white primer before, that might be something to look into. Try putting on another coat and see how it turns out.
