copper

4 friends and me went out for a spin yesterday evening to loomies café, any how, coming home i'm in front doing about 90 on the hogs back (near Guildford) when I catch up a black 3 series bmw that switches on hidden blue lights, Sod it. Policeman slows right down but motions me to pull up next...

I understand is one of the few lubricants to use with caliper pistons but in another thread here, someone said it damages the rubber seals. In the copper grease tube I have, it's specifically indicated for calipers pistons so I'm a bit confused now :dunno
