Listen, I've heard this before, and I'm not impressed. It's the same line you gave in that thread about sealing carbs with RTV after you claimed ''RTV will dissolve on contact when exposed to nitro, end of discussion''. I wasn't so sure, so I soaked plugs of RTV in nitro fuel as well as the individual components of nitro fuel (methanol, nitromethane), videotaped the test and put it on youtube, posted it here, and the outcome was the exact opposite of what you said. It showed no sign of dissolution/degredation after weeks of soaking. That RTV thread went pretty much the same way as the thread ShoestringRacer was talking about earlier, and I've seen that one too.
RTV Does melt under Nitro ...Not a Big Blob...but after all who puts a Big BLOB of silicone on their motor....NO one...you need a bead or thin layer to seal a carb and it WILL debond in a matter of time....believe it or not....like its been said the MFG who makes the darn product said not to use it....what ELSE can you say.
