Few things are more frustrating than starting a build in the back of your classic vehicle (in my case, a Land Cruiser) and discovering a plethora of rust. It’s even more irksome when you realize the cheap butyl mat installed by the previous owner has deteriorated into a thick, chemical-scented goo. By the time that butyl mat is removed and the rust repaired, the last thing you want is another round of adhesive noise mat.
Lizard Skin spray-on insulation is a great alternative to butyl. The company offers Sound Control and Ceramic Insulation for heat. Both are non-toxic, water-soluble, spray on with an air compressor-driven paint gun, and cure in 24-36 hours. The entire process can be completed in two afternoons, while the prep work will easily fill a morning.
The insulation looks very much like a bed liner but is not recommended as a bare surface in heavy traffic areas. Lizard Skin acts as a vapor barrier and will add an extra layer of defense against rust, but proper prevention is still necessary. The sound dampening and thermal reflection properties are truly remarkable. Classic 4WDs struggle the most at highway speeds, but with Lizard Skin, the windows can be down at 65 mph on a freeway in 85°F+ weather, and you won’t be melting or developing severe tinnitus anymore. Available in 1- or 2-gallon sizes; prices below are for 2-gallon buckets.
