I asked because I'd love to know how to restore the bumpers for longer than a few weeks as every product that I've tried does'nt last long enough. Anything oily, waxy etc. seems to improve the looks, I hate the way the grey parts of the bumper go very white

Much cheaper than most common products and great result.
I would like to upload a picture to demonstrate it, but I don't
know how to do that.

That's a grand 'un, that. Does it last as long as the 'proper' products?

It must smell good...
