Pontiac Ink Slate Metallic (87/WA503Q) Touch Up Paint

The Look

This color represents the final, industrial chapter of the Pontiac brand. Whether you are touching up a nimble G5, a late-run Grand Prix, or a Montana, this shade occupies the moody space between a deep charcoal and a stormy, overcast blue. It is a sophisticated tone that avoids the rental-car feel of a basic silver. Since your car has likely been on the road for over fifteen years, you probably appreciate how this finish hides road grime, but restoring that factory depth requires a focused hand and a clean surface.

Technical Details

This is a true metallic finish, which means it relies on millions of microscopic flakes to catch the light. The primary challenge here is mottling, where the flakes clump together to create dark, uneven stripes or "tiger" blotches. If you apply the paint too heavily or too quickly, those heavy flakes sink and pool, making the repair look like a dark bruise instead of a clean fix. To get a factory result, those flakes must land and stay evenly dispersed so the light reflects off the panel in a single, uniform direction.

Best Practices

You will find your paint code on the service sticker located either inside the glove box or on the spare tire cover in the trunk. Before you apply any Pontiac Ink Slate Metallic (verify code 87/WA503Q on the label), you must shake the container for a full minute to lift those heavy metallic particles off the bottom. Test the color on the included card in the garage or shade to see how it matches your weathered panels. When applying, keep the container moving at all times to ensure an even flow of flakes. Give the surface plenty of drying time between layers so the finish sets firmly before you add your final clear protection.
