Replace DOT 3 with DOT 5 Brake Fluid - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Anyone ever changed from conventional DOT 3 to DOT 5 silicone based? I discovered my proportion valve had leaked over the winter and of course peeled the paint right off my inner fender!*^&$%^%^#!!! Bought a new chrome master cylinder with the proportion valve built in and thinking of changing to DOT 5 so I never have to worry about a brake leak ruining any paint. Had one guy tell me flush with alcohol, blow the lines out with air hose, and bleed with the new fluid?
Any other experience, advice, opinions?
Thanks
Kev
