I used it on the unpainted plastic of the bumper without any noticeable color damage after 11 years. However, I noticed a difference when applying it to darker and glossier surfaces. I will see how it holds up with washing, but I can easily reapply it every now and then since it's not difficult. I believe it's worth the money!

Easy to apply with a sponge and then shine with a towel. There is a noticeable difference in the eye. I used it on both the machine and the car and I really like it. Take it without fear, it's worth the money. I had used various things like dashboard polish and similar, but this is the best thing I have bought
