i did that before on my other car. that silver stuff is braided metal that slips over the rubber tubing.
to make it look good you need it especially tight without any stretching or clumping of the braided metal sleeve. i found this extremely difficult to achieve, especially with the radiator hose.
if anyone can really get it show quality, then good job. mine looked alright but i could easily spot the over-stretched areas. i think it's just a pain in the ass to do.
got mine from autozone...
