Match of Sherwin Williams™ SW1803 Ultimate Blue *

Confirm SW1803 Ultimate Blue from a physical swatch or another known existing color reference, not from a screen alone. Screens, lighting, and display settings can shift how the color looks.

MyPerfectColor makes a match to the selected brand color reference, so the key decision is making sure SW1803 Ultimate Blue is the color you actually want before you place the order.

Yes, but plastics vary a lot, so the best approach is to test on the actual plastic part first. MyPerfectColor spray paint sticks well to most plastics, but some plastics need different prep or a primer to improve adhesion.

If adhesion is important for your project, use the MyPerfectColor primer for acrylic enamel before painting SW1803 Ultimate Blue on the final part.

Dry to the touch happens within minutes, but that is not the same as being ready for a second coat or full handling. For a match of SW1803 Ultimate Blue, plan to recoat in 1 to 2 hours.

The finish is fully cured in about two weeks, so avoid treating the part as fully cured until that time has passed.

Before ordering, confirm the SW1803 Ultimate Blue color reference, the product format, the sheen, and the quantity you need. Custom-made color matches are not returnable or refundable, so it is important to verify the order details first.

If you are matching a specific project part, make sure the reference you use is the one you want MyPerfectColor to reproduce.

Clean the metal first, then scuff it so the coating can grip properly. Remove rust, contamination, and loose material before applying a match of SW1803 Ultimate Blue.

Also check the condition of any old coating on the part. Gloss, texture, and the state of the existing finish can affect how the new color reads after it is sprayed.

MyPerfectColor has an original sample of the Sherwin Williams SW1803 Ultimate Blue in its color archive. This enables us to make paint and verify that it matches the original.

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 SW1803 Ultimate Blue, 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.
