for those of you who know what this is can anyone recomend anything i can use to keep it clean and polished like the rest of the car?
i have it on my roof (chav to some of you maybe, but i like it ) and once ive cleaned, ploished and waxed the car it looks really good with the water beading on it etc. untill it comes to the roof where its pooling and making the roof look dull.
so anyone know of some products to use on this stuff to keep it up to par with the rest of the body work? ive put some autoglym super resin polish on there today as a trial but i thought its worth asking to see
