Thanks guys! Drucifier, I like that 3rd pic too, one of my fav shots. Basically when I get to the weathering stages, it's a three step process:
A wash: Consisting of a mix of burnt umber and black artist oils. I slather this everywhere. No filters, and no soaking up of extra wash. I do not gloss coat the whole vehicle prior, just to put on decals. I only add gloss to the areas where a decal would be. Then brush on dullcote over the decal when dry.
Let the wash dry for a few days, then I start drybrushing the hell out of everything. I pretty much use one colour for this, and it's called sandstone, made by either Creamcoat, and Applebarrel. These are acryillic craft paints.
Pastels/Weathering powders. Here I mainly use black and whites. Use chalk pastels, not the wax kind. To save time, I bought one of those big Weekly Medication conatiners...the ones for the days of the week. I have an old coffee grinder at hand so I grind the pastels up into powder, and add them to the little containers. I start adding the pastels/powders here and there to show recesses, etc, and whites to accent.
Chipping - Here I just use a silver coloured pencil crayon, and go everywhere. For my 88 dio, I actually painted grey first, then yellow, and took a knife and scrapped off the yellow to reveal the grey underneath.
"There you go with those negative waves again!"
