AK Interactive Interior Streaking Grime Effects - White

Yes, applying a clear acrylic varnish over your base paint is recommended to protect the underlying finish and ensure the enamel weathering flows correctly.

While formulated for white and light interiors, it can be used on other colors, but the 'white' pigment will appear as a lighter, dust-like grime which may look out of place on dark surfaces.

It is best to let the effect cure for at least 24 hours to ensure all solvents have evaporated before applying a final protective clear coat.

When used correctly over a base coat, it is safe. Avoid applying directly to bare plastic for extended periods to prevent potential surface damage.

Because it is enamel-based, you can completely remove the effect with a clean brush soaked in White Spirit and start over as long as the product has not fully cured.

Your brush is likely too wet. Blot the brush on a paper towel after dipping it in White Spirit to ensure it is only slightly dampened.

Apply less product to the brush. You can build up the intensity with multiple layers rather than applying a heavy coat all at once.

Vary the length and spacing of your vertical lines. Natural weathering is rarely perfectly symmetrical or evenly spaced.
