Thanks for all the responses.
I'm with Ron, WD-40, and Saran wrap get used on just about everything in my life!
6 sets of jacks, no problems, I think that is about as good as it gets..
When I ordered the PC, I was having a hard time justifying the added price for the jacks. After 10k miles its one thing I really enjoy, and I would do it all over again, not so with other options.
