Epoxy Glue for Resin Parts

Bob Smith Industries. I use the purple bottle which is medium thin. This is great for small gaps, and still gluing things together. The thicker get is also great for filling big gaps.

I generally use CA (usually the thicker, gel type) wherever it will work, and it does work fine on urethane resin.  I save epoxy for those places where I need more stength, because it is just harder to use (requires mixing).

Another place I use epoxy is on clear parts.  While CA bonds the clear plastic, it will often fog it.  Epoxy will not fog clear plastic, yet produces a stronger bond than window cement.

I use Gorilla Super Glue Gel and it works within 10 seconds and the part is there to stay.

My preference is to use CA (super glue) on small parts and to hold larger ones in place, and to reinforce larger concealed joins with epoxy. The brands I like are Loctite CA and 5 Minute Epoxy; others will probably weigh in with their favorites and there are other good choices. Mine is based on easy availability and shelf life.

Be sure to wear a dust mask while sanding and wash all the parts well before joining. I use Wesley's Bleach White from the auto parts store and a good long rinse to get rid of any mold release on the resin.
