A match of Sherwin Williams 42186 reads as a very dark, low-chroma blue-gray with a cool charcoal base. The color sits close to black at a glance, but a muted blue undertone gives it more character than a plain neutral dark gray.

MyPerfectColor custom spray paint matched to Sherwin Williams 42186 can be used on HVAC vents, speaker grilles, switch plates, railings, metal brackets, mailbox parts, shelf supports, cabinet pulls, and other small parts that need a dark coordinated finish. It is also a practical choice for PVC pipe, access panels, trim pieces, and removable hardware where spray application gives more even coverage than brushing.

Because this is such a dark color, surface preparation matters. Scratches, texture, old sheen, and patchy substrates can remain noticeable, especially if you are coating only one part next to an older finish. On darker colors, even spray passes and enough film build help the color read more evenly; gloss level will also affect how deep or flat the color appears. On exterior parts, dark cool colors can show weathering and fading more readily than lighter neutrals over time.

Frequently Asked Questions About Match of Sherwin Williams™ 42186 *

Can I return a custom-matched Sherwin Williams 42186 order if I choose the wrong sheen or quantity?

Custom-made color matches are typically not returnable or refundable, so confirm the Sherwin Williams 42186 reference, product format, sheen, and quantity before you order. MyPerfectColor is supplying its own paint matched to the selected Sherwin Williams 42186 color reference, not the original Sherwin Williams paint product.

If you are matching an existing part, also remember that an aged surface can look different from the original color reference, so it is worth checking the target carefully before placing the order.

How long does Sherwin Williams 42186 spray paint take to dry, recoat, and fully cure?

For MyPerfectColor custom spray paint matched to Sherwin Williams 42186, dry-to-touch is usually within minutes, recoating is generally in 1 to 2 hours, and full cure is about two weeks. Those are different stages, so a part can feel dry before it is ready for heavy use or assembly.

If the item will be handled, installed, or stacked soon after painting, plan around the full cure time rather than the dry-to-touch time.

Will Sherwin Williams 42186 spray paint stick to plastic, and should I use primer?

Plastics vary a lot, so test MyPerfectColor spray paint matched to Sherwin Williams 42186 on the actual plastic before committing to the full project. MyPerfectColor spray paint sticks well to most plastics, but different plastic formulations can need different prep or primer to bond well.

If the part is a PVC pipe, vent, grille, switch cover, bracket, or similar item, use the MyPerfectColor primer for Acrylic Enamel to improve adhesion when needed. A test spot is the safest way to confirm the finish on the exact surface you plan to paint.

Which sheen should I order for Sherwin Williams 42186 in MyPerfectColor spray paint?

Choose the sheen for Sherwin Williams 42186 based on how the part will be used, how much reflectivity you want, and how easy you need cleanup to be. Higher gloss usually reflects more light and can make the matched color read differently than a flatter finish.

If you are matching separate pieces on the same project, keep the sheen consistent across them so the finished items read as one coordinated match. The color code alone does not define sheen, so the finish choice is part of the order.

Why can Sherwin Williams 42186 look different after application even when the color match is correct?

Lighting, placement, nearby surfaces, substrate texture, and sheen can all change how Sherwin Williams 42186 reads after it is sprayed on. A match that is correct on paper can still look different once it is applied to metal, plastic, wood, or a previously coated part.

If the item will sit next to an existing painted surface, compare it in the actual location and lighting before approving a large project. That is the best way to judge the finished appearance of a custom-matched Sherwin Williams 42186 part.
