Chipping............................
Where do you start................................
Using a primer as part of the chipping is probably better with hair spray/chipping solution, I have just watched a PanzerMeister 36, video which was quite good using both red primer and dunkelgrau chipped back from a dunkelgelb Stug III for an Afrika Korps build, a Bronco Stug D with an L43 barrel
The brush/sponge chipping is usually a lighter version of the top colour then a smaller amount of Vallejo 822 Black brown camo inside the lighter bits, leaving a small amount of the lighter colour around the edge.
Something like Night Shift, but not 70 + hours worth.
Its too easy to overdo it, so a little at a time, water the paint down slightly and step back from it regularly to see how it looks.
Marcus Nichols, the
Tamiya magazine editor, has a really good DVD out too, from 2008, it should be on you tube too?
Again its another practise, practise, practise thing, I shall review my Stug after having left it for a few days, and look at it with fresh eyes
Loads of stuff on you Tube to give you some ideas, but keep it simple
HTH's?
