 EZ84 is a 2-part structural epoxy.&nbsp;&nbsp;The resin is clear in color, and has a tendency to form crystals with age.&nbsp;&nbsp;The crystals can usually be reabsorbed if you immerse the container in very warm water.&nbsp;&nbsp;The hardener is honey colored when new, flowing quite easily, but turns to a dark brown and molasses consistency with age.&nbsp;&nbsp;Old hardener can be made to flow better with carefully applied heat, such as with a paint gun.<br/>

 Temperature is critical for epoxy chemistry, and is often stored in a hotbox.  It's best to maintain the part and the epoxy above 70 degrees Fahrenheit or so (see also post-cure).  Measure the needed volume in the appropriate 44:100 ratio (by weight) or 47:100 (by volume).  Most people choose to get a ratio pump such as Michael's, though you can get ratio-dispensing jug, or use a high-accuracy scale.
-Good mixing is critical for epoxy work, but not that difficult.  I find it easier to to mix with a tongue depressor with the end cut off square (with a pair of old, dull scissors) so I can scrape the sides and floor of the cup liberally.  I typically mix for approximately 30 second to one minute, depending on the volume I've dispensed.
