Becareful on the Victor Reinz crap, 3 out of 4 of my regular parts vendors all carry that stuff under the Volvo part number and it is not the correct sealant. It is just a tube of RTV silicone. The correct stuff is closer to Elmer's glue in consistancy and is orange to hot pink in color. Application is as simple as painting, squeeze the stuff out onto a clean surface, load your roller up with it and then paint the perfectly clean and prepped surface that you are going to reseal. I've done a bunch of those 960 pans and I still dread doing them, the front wheel drive cars are much easier, some of the late model ones are so easy as to borderline on fun! As far as what to use to apply the stuff, just get one of those small (1" diameter) short haired rollers and you will be fine. I use a dremel tool with a wire cup brush to get to the hard to reach areas on the bottom of the block to clean the old sealant off with. There will be one spot on the inside of the block that will pretty much continuously drip oil while you have the pan off, it is back by cylinders 5&6 and will be on the exhaust side. Let it drip as long as you are working on cleaning stuff up but when it comes time to install that pan make sure that you wipe the inside of the block where the oil runs down as far up inside of the engine as you can so hopefully none of that oil will contaminate your seal area. Also, before you paint that sucker up and go for the install, do a couple of dry runs to get the feel for how that pan is going to go back in. When you are comfortable with putting it in and out without messing up your sealing surfaces then wipe it all down real good, apply your sealant, recheck that spot that always drips oil and install the sucker. Something else you might wonder about is how long do you let that stuff set before you put oil in it, while I have never seen a hard and fast number for a wait time from Volvo, I have seen plenty of those pans slammed into place, stuffed full of oil, twist the key and bring up to operating temp with no ill effects on the sealant.
