Yes, you can apply multiple layers of Tire+ to your tires for an even higher shine. However, it's important to allow the first layer to dry completely before applying the second layer. This will ensure that the product cures properly and provides the maximum shine and protection for your tires. With each additional layer of Tire+, you will enhance the hydrophobic barrier and repel dirt and moisture more effectively, keeping your tires looking clean and presentable for even longer.
