DOT5 wont, yep, its silicone based, but DOT5.1 isnt and will strip it :) I'd give DOT5 a try if i had some :)
When i was looking at brake fluids for bleeding my bike brakes it said dot3,4 or 5.1, couldnt get DOT3 anywhere, im guessing around here at least the motor factors have taken the fact that its more pricey to use the newer stuff and decided to only supply that. So i went for DOT5.1, why go halfway with safety eh? :)
