    silicone gasket drying time

    i just redid my front differential gasket with silicone in my truck, it was leaking pretty bad. i didnt have plans to use my truck for a day or so but something came up unexpected and i need my truck. how long do i need to wait before i can refill with gear oil and start driving it. i dont wanna have to do it again. back of tube says 24 hours for full cure?

    I don't wait at all, slam it , fill it and go..
    I use the silicone for gear oil.
    I do not let it set at all before assembly.
    My surfaces and and bolt holes are surgically
    clean. Wire wheel bolts.
    Never had a leak if this is followed, I do hundreds
    each year.

          Ring ring....ring ring, Hello, room 209 please. Hello sir, this is the shop with
          your pick up. Yes, we found the leak, it was the differential cover, looked like
          it rubbed over something and broke the factory sealant. My technician has resealed
          it but you will have to wait until Monday to pick your rig up. Sir..sir, please calm
          down, I know this is not even lunch on Friday....Sorry about your Bass tournament
          tomorrow ....No I don't know how much money and TV coverage you get...Sir, please
          listen, I know all the other shops in town do differential services in less than an hour
          but my technician is just out of the best automotive college in Arizona and he pointed
          out that the sealant we have always used will not be fully cured for 24 hours and we
          are not open during the weekend. Fire him???!! Me do it!! I can't, I'm
          fishing in a Bass tournament tomorrow!! Have a nice weekend!

            RTV = Room Temperature Vulcanizing

            This means it will "set-up" at a thickness of 1/4" in 15 minutes of drying time. I have never waited for RTV to "full cure" in 25+ years of auto mechanics. I guess it depends on what you are using, but the typical RTV Silicone gasket maker/sealant like Permatex Ultra Blue, Black, Red, etc. are good to go by the time you get the bolts tightened.
