I discovered this myself several months ago. Thing is, its not permanent. At least not in my experience. I began to notice it fade in streaks. Not real bad mind you but noticeable all the same. It turns out to be a semi-permanent coating in the end. I figured that if I were to touch it up every few months I would end up with a thick coating that would peel and look even worse than the old-faded bumper.

If I were you I would spend the money and get some of that spray paint that body shops use. I can't think of the name of it now but it is way better than krylon, rustoleum or other common store brands. Not cheap. I spend about $18/can at a nearby auto body paint store. Of course now you'll have to spend the extra effort in removing the shoe polish before applying it.

How long has it been holding up?

I've got to give some cosmetic lovin' to our 740's bumpers.

...Of course I've still got to put the front suspension back together again. :-)

Thanks!

Would you be able to post pictures with some close ups in the light? Sounds good for $5 or less. I wouldn't mind trying it out.

My bumpers are grey.

Are they supposed to be black?

Thanks
