I highly recommend using Permatex Ultra Grey or Yamabond #4 when sealing crankcase halves, gear box covers and applications that require no gaskets – on the flip side, both Permatex Ultra Grey & Yamabond #4 are NOT compatible with gas

Easy to apply and also easy to remove – many sealers on the market are hard to apply and even worse to remove… We use both of these sealers in the workshop on a daily basis with excellent results
