velcro is a couple of quid a metre from any haberdashers fella, if you cant find any weve a good one here ill get you some and post it up to you
As for the brake guards, I personally would rig one with just a small corner in bleach for a while and see what happens, then try a bit of it with the print on as well to see if it efects it, I cant see why you cant bleach one, ive had a crack at bleaching most plastics and theres always an improvement afterwards, cheap thin blech i find works best
