I like to use a high temperature hot melt like the Bohning Ferr-L-Tite. Most of the tan or amber colored hot melts tend to have a little higher heat reistance that the whites or clears. You can find the Bohning hot melt in the archery section at many sporting good stores:

5 min Epoxy will work for bonding tips and I know a lot of folks use it as well. It will take more heat and work to remove than the hot melts, so if you need a repair, you just need to be more careful when working to remove it (try not to twist).
I've measured a a some of the melting points, and here's a list of a few that'll give you a good idea of the temp range that you'll see.
JetMelt White= 167F, FlexCoat= 187F, Bohning Ferr-L-Tite= 216F, Jetmelt Tan= 220F. ...again take off about 30-40 degrees to figure heat resistance.
Most of these hot melts have a broad melting range, and the temperature listed is the peak melting which relates to where the material will melt flow. The heat resistance temp is generally about 30 to 40 deg below the melt. Very generally speaking, the melt temp will increase as you go from materials that look clear, white, yellow, amber and tan.
One of the ultimate in high temp hot melts is Jetmelt 3779, which melts at 325F and has a heat resistance up to 300F.
So consider a scenario such as a hot car which can easily see temps of 120-130F in a short time, and in extreme cases up to 150-160F. I’d say you want to a very minimum of the type that Flex-coat sells, maybe higher if you’ve got concerns about high temps or had any trouble with adhesion.
hope that helps,
