I use this alot. It works for all types of materials (glass, metal, silicone, rubber, latex) and doesn't gum up or smell. Fantastic product.
System Jo Hybrid Lubricant - 8 ozthis is the best lubricant i have ever used. it is not greasy. it only takes a small amount. it is not too slippery. it doesn't smell or taste bad, either.
Good stuff, easy to clean up. Excellent multi-purpose lube.
