AS5 should work well. In fact, in this TIM review it scored very near to the top in a field of 80 tested materials. Always take reviews with a grain of salt, but at least now you have something to read through so that you can make the determination on your own.
Hope this helps.
Edit: Note that AS5 has an ~8 day curing period, so don't fret if the temp isn't right where you want it to be immediately after application.
