I had a nightmare with one of mine a few years back, and tried everything including plenty of heat, but only one bolt budged half way then snapped on me, so rather than ponce about I bought another used wheel and got the tyre changed as I needed the bike back on the road asap due to it being my only transport.
As with most things it's not always that simple, as there's heat and then there's heat! The issue is the amount of thread lock applied to the bolts this is a very hit and miss, some have hardly any, a lot have way too much![size=1em] Most use a butane blow lamp type that screw in to a can, they don't provide enough heat to tackle the stubborn over coated bolts. [/size]The 2 ways I remove stubborn bolts is to use acetylene, or for when owners have tried all the normal stuff and rounded the bolt head and the hex key, I cut a quality hex key down a weld it into what's left of the bolt. The heat from both methods quickly penetrates down the bolt melting the thread lock, butane can't deliver enough heat, the heat it does produce ends up being dissipated through the disc/wheel which can bugger the finish on both even distort the disc carrier, but do absolutely nothing to the thread lock.
