Default Re: Got myself a Metadyne Thumper (No. #157)

Hmmm... odd. It's nice that they designed it for petroleum -- but it was my impression that not only can petroleum jelly harm synthetic o-rings but it's also far less consistent from brand to brand than white lithium or dow33. Make sure you only use jelly without fragrance or other additives that are designed for humans (lotion etc).
