squeeze tubes (stores better/longer). Buy an extra pack too - just to make sure you have enough. Good stuff to have around too for other repairs (like a nick in the t-top weather strip molding).
Works fine for what you need to do - stays flexible. Key to this job is all the prep/reinforcement done before applying the 2 part epoxy. Once applied - can easily be sanded/shaped and be sure to use spray paint with flex additive mixed in (or your shop will do it)....
