Hi all,

Bought this sponge from BMW at the same time as some touch up paint.

Described as a vinyl and plastic sponge. But not sure what exactly the yellow part is for, well apart from scratching everything it touches!!

[....,,,,..,,..]

Tyres applying tyre gel.
That's about all it can be used for I think.

I think it's supposed to be a fly remover, probably designed before they used watercolour paint on their cars.

Honing the cylinders?

[335i nthehouse]

Smoothing uneven road to hide the run flat ride quality?

Or maybe to sand down the orange peel effect!

Nearly!
I think it's for removing flies/bugs from your windscreen. I had one free when I bought a few bmw bits from eBay a few years ago although mine is a solid yellow sponge. Not really used it.

I doubt it would scratch the windscreen. Think about when you use an ice scraper in the winter.

I now have 4 of these useless jobbies, I use on the alloys sometimes but nit the yellow side

I use it for sanding down our wooden floor ready for varnishing.
