Toyota Finish Line Red Tricoat (3U9) Touch Up Paint

The Look

This is a loud, high-energy red that Toyota used to signal a new era for the Crown and the refreshed Corolla. It is far more sophisticated than a standard flat red. On the road, the color reacts heavily to direct sunlight, shifting from a bright, punchy crimson to a deeper, more elegant ruby in the shade. Because your car is likely a newer model, the factory finish still has its original depth, which makes a proper touch-up vital for keeping that premium, metallic look intact.

Technical Details

You are dealing with a tri-coat finish, which is more complex than a basic single-layer paint. This system relies on a solid base layer followed by a translucent midcoat that contains pearl and metallic flakes. The danger with this finish is mottling, where the metallic particles clump together and create dark streaks or uneven spots. This happens if the paint is too thick or if the flakes are not distributed evenly. Getting the match right depends entirely on the thickness of that middle pearl layer, as more coats will gradually darken the final appearance.

Best Practices

Open your driver-side door and look for the silver or black identification sticker on the jamb; your code is listed next to the "C/TR" prompt. Before you spray or dab Toyota Finish Line Red Tricoat (check for code 3U9), you need to shake it for 60 seconds. This is the only way to ensure the metallic flakes are suspended properly rather than sitting at the bottom of the container. Test the color on the included card to see how many midcoat layers you need to reach a perfect match. Keep the container moving to prevent the paint from pooling in one spot, and allow plenty of drying time between each thin layer.
