Radio Shack sells heat sink paste for computer cpu's, that's what I'd use. Shouldn't cost more that a few $. Just take the EZL off the inner fender and scrape the old stuff off. Put a thin layer of the new paste on and reassemble. You don't need a lot, just so a bit gets squeezed out the sides as you tighten things. This will probably extend the life of your EZL.
