Did my own PR casting using the carbon fiber sleeve. I've had a gallon of Silmar 41 on the shelf for about a year; I really thought it had surpassed its shelf life, but went ahead and used it. Degassed the PR with a vacuum chamber prior to pouring. No pressure pot used. Also created my own mold using mold putty I bought from Hobby Lobby. 24 hour cure and pleasantly surprised to find no visible bubbles.
