How do you open Castin’ Craft resin cans? Ok. I have this can of Castin’ Craft brand polyester resin that is brand new. I unscrewed the top and was confronted with a second metal barrier:



I’ve tried:


Prying it with a screwdriver.
Grabbing the edge and unscrewing.
Putting pressure from the inside and unscrewing.
Stabbing it.
Focusing my chakra, prana, and kundalini energy to visualize and create a portal through which I can pour out the contents.
Yelling at it.


Before I just take a step bit to the top of this can, does anybody who’s used this resin know how to open this?

I know this might be a silly question but I’ve never had so much trouble opening a can before, and believe me I’ve opened a lot of cans.
Prying with a narrow screwdriver is a good start. It appears in the photo that you have a bit of a start at the near edge of the top.

This particular seal is a throw-away and you can indeed stab it. Something stronger than a pointed stick should do well enough. A small blade philips screwdriver tapped in then bent outward will distort the top sufficiently to pop it free.

Be not afraid, plunge onward!
