Review on 🛁 Fiberglass Repair Kit - White/Almond/Black/Bone/Bisque/Biscuit/Grey/Cream/Off White/Beige, Odorless Tub, Tile, and Shower Repair Kit with Bathtub Paint/Porcelain Repair by Matt Heringer

Especially with almond and beige tones, the following technique should be included in the instructions: Mix a very small amount of yellow with a small amount of a mixture of 50-50 A and B, and do the same with a separate blend with black. Then prepare the 50-50 amount of mix A and B that you will need as the third mix. Finally, add a small amount of the yellow mix and the black mix to the third mix to get the desired finish color; do it in small steps. If you add a lot of color mix, you will have to add more A and B and add more color mixes as needed, but that's much easier than fixing a single mix.
