When to Use Blending Clear Coat?
4 Answers
Apply the blending clear coat within 3 minutes after spraying the glossy clear coat. The blending clear coat only needs to be sprayed in 2 to 3 layers at the interface between the new and old paint, at a distance of about 15cm. After car paint repair, there will inevitably be some color difference between the repaired paint and the original car paint. At this time, the blending clear coat is needed around the repaired area to create a transition and eliminate the visual color difference. The glossy clear coat is used to beautify and add gloss to the paint surface after repair. Precautions for storage and use of blending clear coat: 1. Mixing ratio: Ready to use without mixing; 2. Spray gun pressure and tools: Gravity feed spray gun with 2bar pressure and 1.2 to 1.5mm nozzle, suction feed spray gun with 1.4 to 1.7mm nozzle; 3. Application method: After completing the paint repair, lightly spray a layer of blending clear coat at the interface immediately, then lightly spray another layer after 15 seconds; 4. Suitable for: 2K topcoat, two-component clear coat; 5. Not suitable for: 1K base coat; 6. Shelf life: Can be stored for more than 2 years when tightly sealed, storage temperature is 20 degrees Celsius.
I often encounter this situation, especially when helping friends deal with minor scratches. The blending clearcoat is actually used for transition areas after spot painting, mainly to solve the problem of overly obvious joint marks between new and old paint surfaces. For example, if a small patch of paint is scraped off the rear bumper, and only that small area is repaired, applying blending clearcoat at the junction of the new and old paint can make the colors blend naturally, making the repair almost invisible. Remember, it must be used after small-scale repairs and before the clearcoat is applied. Spray it thinly along the edges of the repaired area two or three times, gradually expanding the spray range to create a natural color gradient. After spraying, the overall appearance will be much more harmonious. However, it's best to let a professional handle it, as spraying too thickly can cause whitening or discoloration.
After repairing car paint several times myself, I figured out that blending clearcoat is the secret weapon for localized paint repairs. For example, if your car door accidentally scrapes against a pillar and leaves a palm-sized paint scratch, the usual repair involves sanding only the damaged area and then repainting. However, you'll notice a stark color difference at the edges after direct repainting. This is where blending clearcoat comes in—after applying the base color but before the clearcoat, spray the blending clearcoat from the edge of the new paint outward to create a smooth transition. This helps the surrounding old paint blend naturally with the new color. Remember to reduce the spray pressure, maintain a distance of about 30 cm, and apply quick sweeping motions for a seamless transition. If you're unsure, it's better to leave it to the professionals for peace of mind.
Last time when my car got chipped by a pebble and went for repainting, the technician specifically mentioned the timing of blending clearcoat application. It's an intermediate step in the repair process, specifically addressing the transition between the spot-repainted area and the original paint. Immediately after spraying the color-matched paint, a thin layer is applied to the edge areas, serving as a softening treatment between old and new paint surfaces. The technician uses a misting spray technique, allowing the new paint color to gradually fade out like smoke into the original paint, making the color difference virtually undetectable to the naked eye. However, with special body colors like pearl white or metallic paint, the blending effect isn't as easily achieved as with regular paint.
