Wow,thanks for the great and detailed post! I need to re-bed a lot of hardware soon,and had not known there was another option other then 5200 or similar. I also like the less mess, and assuming no drying time. This will be very helpful as I am a long way from my boat and would like to be able to re-bed things when I have time without worrying about the mess and drying time.
I do not quite understand why an impact wrench would take the nut off the bolt without twisting the bolt. Is this just due to the friction on the top, where the sealant is holding the head, and that an impact wrench needs less friction to hold the bolt then a regular wrench?
I see an impact wrench in my future whether I understand the concept or not...
Thanks,
Bryan
