I have a new 2021 Mazda GTR which I purchased with the cash I saved by not drinking any alcohol for the past 18 years-thank you AA. For the past 20 + years I have used and liked NuFinish and it has served me well. I am especially pleased with the ease of applying and removing, the longevity and the finish. Using these three attributes, should I be looking at another protectant / wax etc. Ed
