Reflector: MGS Epoxy

[Kufalk]

Jim,

What kind of MGS resin and hardener do you use/recommend to replace the
EZ-84 stuff?

My pump is just about ready to be cleaned out again because the EZ-84
hardener has turned to sludge.  This last batch lasted only 7 months.  I
don't want to buy any more.  I am finished with everything structural.  I
just have a few odds and ends to lay up, interior trim pieces and some
lay-ups on the engine cooling plenum.
