I've noticed on several helmets (mine included), that when the silver and grey weathering paint is added topically, the paint tends to streak or bubble. You can see the brush strokes, and feel the paint layers with your fingers.
Is there a way to weather topically, that doesn't have this effect?
Here's a method I was thinking of: After the primer and silver base coats, hand-brush the grey weathering areas. Then hand-paint all the primary helmet colors, greens, reds, yellows, what have you, painting around the weathered areas, allowing the silver and grey to show through. Obviously at this point, you will see brush strokes. However, I was thinking if you use a fine-grit sandpaper (very small circles) and sand down these imperfections, you'll get the desired 'layered' look, without all the brush strokes and silver paint blobs.
Has anyone tried this? Pros and cons?
