After I complete what's called Decontamination I applied the 3D Nitro. The application process was time consuming but fairly simple after watching several 3D Product Videos on 3D Nitro. After applying Part A and Part B I waited 1 hour and removed with Kit provided Microfiber Towel. Car remained in my garage 48 hours to cure. The shine definitely increased throughout the 48 hours. NOTE: An issue I had, which wasn't addressed in 3D Product Videos or 3D Nitro Instructions was shake Part B vigorously. There are very small beads that must be mixed with the fluid inside the Part B canister.
