VS profelt and glue adhesion, follow-up

[Porritt, David]

Barb:

I've heard people swear that silicon made it impossible to glue
anything.  This would be your chance to test that theory.  Try protec,
McLube, and I'm sure you have some Pam in the cupboard!

Hi all,

I wonder what there is out there in the world that would make new
bushings not stick?  Could it be some other lubricant that someone used
on the old bushings, or maybe a concoction used for removing old
bushings?  

Anyway, I'd like to test a lot of different products--anybody want to
make suggestions of chemicals I should try?  E-mail me privately if you
wish.   

Thanks,
