Ok here is another good one.
This is an eye liner brush.
Steal one from your chick/wife/babe or just go to the 99 Cent store and buy a few of them. This particular one is the PERFECT width for nearly EVERYTHING that gets gasket sealer on our engines.
If you look closely at the opposite end, there is a rubber spatula which is AWESOME for getting the extra goo out of the small oil passages like the ones in the cam caps as you will see in the pics below.
As you can see below, it does a fantastic job of spreading the Fuji Bond 1215 along the mating surfaces. It is also perfect for the oil pump mating surfaces and also for applying sealer to the threads of specific bolts that REQUIRE sealant as outlined in the FSM.
Does a great job of allowing you to keep your fingers clean while you spread out the bond, and the brushes will last a while. You just clean them up with brake cleaner and a rag and they are good to go the next time you need them. The biggest advantage to these particular brushes is how short the bristles are. They are relatively stiff so it makes for a nice smooth, even bead without the mess normally associated with this task.
Perfect bead, every time!
