"The Heat is On" -- ALERT

For those who want to know the product is made from orderless mineral spirits and a mixture of various types of silicone. It will dry out over time. However if you keep applying it the silicone will keep the surface moist and slick. The solvent is used to aid in quick drying of the material when applied.

Tire wet is very similar. Have you ever noticed how your tires look after a few days in the sun? Discolored and faded.

You all are an intelligent bunch you figure it out.

Silicone is may not the agent for the drying, I feel it is the solvent. So look at the materials used in the mixture. Frankly I would ask questions about this topic to the speaker designers. They would have a better history in dealing with this topic.
