It should adhere to the resin.

How well did you shake your spray can?

Hmm.. maybe not as much as I should have I will try again.

Shake it for at least 30 seconds

You can also dip it in some warm water.
Not hot, just warm. It will make the spraying smoother

Be sure to thoroughly wash the piece with warm soapy water before trying to prime it.
