Yes, our Multi-Surface Paint Touch Up will work for this application. Please note that this is a matte [low-gloss] paint. If your surface is glossy, you may prefer our Appliance + Porcelain Paint Touch Up, or you may wish to use our Multi-Surface Paint Touch Up but finish it with one of our Clear Touch Ups.
Because porcelain surfaces are so smooth, we recommend that you gently scuff and/or sand the spot first (this will allow for best adhesion), and of course you will also want to clean the area (perhaps with our Shop Cleaner + Degreaser or our Multi-Surface Spray Cleaner) and thoroughly dry the area, to remove any dirt, dust, grease, water, etc., for best results. We also recommend at least two coats, and you may want to do several coats, letting it dry 1-2 hours between applications, for maximum durability.
If the damaged area is not very deep, that is all you may need to do. If there is an indentation or groove, the paint will visually cover the spot, but won't fill the indentation, so you may wish to use a filler such as Soto's Appliance + Porcelain 8-piece Epoxy Repair Kit to fill in the spot, and then cover with the paint to hide the defect.
Soto's Multi-Surface Paint Touch Up comes in 24 different colors (12 in our neutral palette, and 12 in our pigmented tones). If you need a glossy finish, you will want our High-Gloss Appliance + Porcelain Touch Up, which comes in our 12 neutral colors plus 5 pigmented tones. To see which is the closest match, please order our color chart, so you can see our colors in person, since different computer/phone screens show colors differently.
