@SIRT posted:All clear coats will dilute colored powders except black soot. It will also eat colored pencils and chalks. Details like rust and marks have to be hand done using acrylic or oil-based paints. I recently started using oil pastels for certain rust marks. Both are not affected.
I apply colored pencils to the roof and wood grain areas last after the clear has been already applied. No need to coat or seal them.
Very true Steve. The black is about all you see on the roof of my caboose. I had a more streaks and marks on there before the spray ate them for lunch....
