Shiny Car Stuff is essentially a high gloss, self-leveling clear coat that is hand-applied to your vehicle. It helps improve the appearance of old, damaged, fading clear coat, headlights and trim. It also adds a long-lasting layer of depth along with rust inhibitors and UV protection. Shiny Car Stuff is applied by hand with a folded shop towel or micro applicator. Please follow our full Step-by-Step Instructions here: https://shinycarstuff.com/pages/how-to-use We estimate for an 8 oz bottle is approximately 1-3 average-sized vehicles. However, the larger the car/the more damage/the thicker the coat you apply, the more product it will take. It may require multiple coatings which you can reapply after 48 hours between applications. How Do I Remove SCS? If there is a significant mistake made in the application of your coating and you need to remove it – stripping the coating is much easier within 15 minutes of initial application. If you need to remove the application in that 15 minute window, we recommend scrubbing the coating with Wax and Grease Remover. If you need to remove the coating after it has already cured, you will need to wet sand/heavy cut with a rotary/elbow grease with a heavy solvent. This is a long-lasting coating.
