I use Alot of E20HP, so much so I buy it in 200ML cartridges and have the gun to go with it (its like the 50Cal of hysol guns). I use it for closing up composite molds with structure inside as well as general installation of parts in fiberglass and wood models. The slighly runnier state of E20HP allows it to soak into wood parts giving IMO a better bond. 9462 i use for bonding things with higher loads imposed on them and for filleting.
