I poured the resin two days ago and it is mostly cured but the
surface appears a bit rubbery and tacky. It is a bit humid here. I
dont know if that makes a difference or not.
I believe that means it will never cure up, and you need to dissolve
the epoxy out with Attack (OUTSIDE!) and re-do it.
I have found that putting a lamp down close to the epoxy helps get
the bubbles out.
You can also call Rio and ask for tech support, they answer
questions about their products.
