I've been testing and using 303 Protectant, which I tend to like very much. I recently purchased a bottle of Optimum Protectant Plus to compare against the 303 Protectant.
I thoroughly cleaned my dash with a woolite / water mix, then used a clean micro fiber towel spritzed with distilled water to remove any remaining woolite soap film. This worked perfectly and left my dash absolutely clean and ready for the OPT Protectant + application.
Overall I find the OPT Protectant + to be fairly similar in appearance to the 303 Protectant. This is what I was hoping for.
Need to do a bit more testing to finally make up my mind. However I am leaning towards the OPT Protectant + now, and if this is my go to vinyl dressing, I will purchase a gallon of it for my detailing business. The OPT Protectant + is half the price as the 303 in the gallon sizes.
I know it makes a difference as to the types of applicators one uses to apply the vinyl dressings. Some applicators just work better and provide a more even application.
What are your favorite applicators? Small micro fiber covered sponges?
Cheers,
