Before F11 is applied, make sure your bike, vehicle, or surface is cleaned first. You can use any products to wash but preferably use products without wax in it, or any synthetic “coating” for “protection” as the F11 won’t bond properly on the first application. However, each application of F11 will push out any other coatings that were there and F11 will eventually bond 100% to the substrate. If you want to add several coats of F11 to your surfaces, wait at least 24-48 hours between coats to ensure effective performance. Multiple, consecutive coats can be applied, but you will not achieve the benefits as you would by allowing one application to “set up” or “cure” first within the stated time frame. Clay Bar: If you have any contaminants in the paint, overspray, or hardened fallout where you need or want to Clay your paint, you can clay the surfaces and use F11 as the lubricant, thus claying and applying a layer of F11 in the same step. F11 works amazing with clay bars.
