Match of Sherwin Williams™ SW7646 First Star *

Coverage for a match of SW7646 First Star depends on the surface size, texture, hiding power, application method, and how many coats you need. A typical can of spray paint covers about 20 square feet with one coat. Other MyPerfectColor paints typically cover between 400 and 600 square feet, but rough, porous, or uneven surfaces can reduce that coverage.

If your project has edges, cutouts, or a surface that needs more than one coat, plan extra material so you do not run short before the job is finished.

The SDS is tied to the MyPerfectColor product and chemistry, not to the SW7646 First Star color name alone. Check the MyPerfectColor Safety Data Sheets page for the exact product format you plan to order.

If you are comparing spray paint to another MyPerfectColor format, use the SDS for the specific product you will receive, since the safety information can differ by chemistry.

Before ordering a match of SW7646 First Star, confirm the target from a physical Sherwin-Williams swatch or another known existing reference. Screen viewing alone can be misleading because lighting and display settings can shift the color you see.

MyPerfectColor matches the original brand color reference, so the safest order is based on a verified swatch or known color standard, not a photo or screen image alone.

Yes, but surface prep matters. For a match of SW7646 First Star on metal or over an old coating, clean off grease, dust, rust, and other contamination, then scuff slick surfaces so the new coating can grip better.

The gloss, texture, and condition of the old coating can change how the finished SW7646 First Star match looks. Depending on the substrate, a primer or sealer may also be needed, especially if the surface is bare, damaged, or difficult to bond to.

For spray application of SW7646 First Star, use light, even coats from a consistent distance and overlap each pass slightly. Avoid heavy wet passes, which can cause runs, uneven sheen, or a muddy-looking build.

Build coverage gradually and let each coat flash or dry according to the product directions before adding the next coat. That approach is especially important on edges, textured parts, and small fixtures where buildup shows quickly.

Please note that if your material is not new then the paint may not work for touch up as your material has aged and is likely different than it was when new.

If you need a touch up application, send us a part and we can create a touch up solution precisely matching the current color and sheen of your specific materials.

While MyPerfectColor can provide paint matched to the Sherwin Williams SW7646 First Star, we don't provide any crossover information because this is a subjective determination. Every paint company offers its own unique selection of colors and rarely does a color have an exact equivalent in another company's color collection, so determining which color is the best approximation is a judgement call.

However, under the color image on a color page there is a link that says "Explore Related Colors". Clicking this link displays colors with similar values and you can look for any colors from the company you want.

Keep in mind that this just shows similar colors based on the color values we have stored in our database. It doesn't mean it is the same or give any approximation about how close the color is. You can play around with the Hue, Lightness and Chroma sliders to expand the selection.
