Chevrolet Transition Blue Effect (WA400P) Touch Up Paint

The Look

The year 2007 was a bridge for GM design, and this color reflects that shift. You have a rare shade that had a very short run on the road. While it appeared on the Avalanche and Captiva, you are most likely seeing it on a Cobalt or Aveo that has served as a reliable daily driver for years. It is a mid-tone blue that stays humble until the light catches the metallic particles. Since your car has likely lived outside for over a decade, the original depth might have changed, but this color still holds its character well against age and road grime.

Technical Details

This is a metallic finish, which means the paint relies on tiny flakes to create its signature glow. Metallics bring a specific challenge: if the paint goes on too thick, those flakes sink and cluster. This creates dark patches or stripes that ruin the uniform look. The benefit of this blue is its ability to mask minor surface dust, but the trade-off is that it demands a steady hand. You want to build the color with thin layers rather than trying to hide a scratch in one pass.

Best Practices

Find your identification sticker to verify the color. On the Avalanche and Aveo, look inside the glove box. If you have a Cobalt, check the trunk floor under the carpet. Before you spray or dab Chevrolet Transition Blue Effect (check for code WA400P), shake the container for sixty seconds to mix the metallic flakes. Work in a garage or the shade to keep the surface cool. Test the color on the included card to check the match against your weathered paint. While applying, keep the container moving to prevent the paint from pooling. Give each layer enough drying time to set so the next pass goes on smooth.
