Here's a question... I read somewhere that diamond polish extender oil is just light mineral oil. Can anyone confirm or know any different? Also, does anyone see anything wrong with using glycerin? Any other suggestions of an oil I can use in it's place? I did hear something about using Vaseline...

I'm not sure but it sure looks and feels like light mineral oil, at least the stuff I have does. Amber has some dark brown oil that is thicker. I think you'd be fine with the mineral oil, don't know about glycerin but I'd think vaseline would be too thick.

Thanks for your input Tony. Does anyone know if glycerin will work?

What I've used was silicone oil, and most of the adv. say silicone too.
I've use oil and silicone spray with a well salted (diamond well worked into) pads with good success.
Mineral oils will create more heat (more friction), so it's depending on what your polishing.
Vaseline's viscosity changes too drastically to work properly, and it's a petroleum based product which some stones don't react well to also (staining for example).
Glycerin is hygroscopic and will draw water from the stone (bad for Opals). It can also give a hazy look to other stones for this reason.

Spray silicone. That's what I use. Spray the wheel with silicone and while it is wet I work in dabs of diamond paste or powder with my finger. And spray some more if it dries out before I get all the dabs spread in like I want. Same for my leather side mount pads. Then every once in a while I spray down the wheel..maybe every few sessions. You want a good silicone...as some have weird additives. I get a good quality automotive spray. T

Great question, one I'd been meaning to ask too. Any advice on building up a good base on the cloth pads? I've got a flat lap and have not yet been able to truly break in the felt or cloth pad (seems like cotton to me but I'm not sure), and not sure how much of diamond paste I should use, how wet it needs to be, how much silicone spray, what kind of silicone spray, etc. Not meaning to jack the thread but seems after Tony's post a good place to ask this beginner's question. And thanks NatureNut for starting this thread!

Well, I've got 6 1/2 inch wheels and I put a dab every few inches down the middle of the wheel. Maybe a bit bigger that a pin head. Then I rub it into wet silicone using a circular motion. I want the stuff to spread out to the edges and far enough to meet the next dab of paste. With a side pad just dot it so it looks like a good case of small pox. Keeping it wet with silicone spray helps spread the paste. Same with dust, but since that stuff tends to roll off, I just do a small space with it, rub it in good, then move to the next space. Both vehicles go a long way so use very little dust or paste until you get the hang of how far it goes. It doesn't take a lot to get a good base, and if you aren't satisfied you can always add more. Be sure to wash your finger good between grit sizes, lol. And don't be sniffing the silicone too much ![:)](//storage.proboards.com/forum/images/smiley/smiley.png) I do the work outside so I don't pass out. T

Haha... another hazard to watch for Tony! No problem on the jumping in, Robin, the more the merrier! Glad to hear I can use it for cloth and leather 'cause I have both. Thanks! Jo
