![]() The finish was extremely durable holding up exceptionally well to the gasoline. I went with flat latex because it more closely approximated the paint job that was on the planes of that time period and the color match was easy with the mixing at the local stores, This P47 was powered by a 2 stroke gasoline engine of 62cc. The entire aircraft was polyester fiberglass primed with automotive primer. This was a scale WWII P47 with a wing span of 86 inches. The doors and roofs and tailgate are important to stop the vibrations/drum effect from bumps etc but just the hum of the road and engine you gotta do the floors and firewall.I have used exterior latex before to paint a radio control airplane. The vibration and noise from the road comes through the floor and firewall more than the doors and quarter panels. Won't do full coverage but if I can will pick the larger flat surfaces to target.įloors and firewall are important. I would them to the back side of the inner door skin. I may look at some of the tiles to get for the doors as well. If I have enough left will do floors and firewall. Will get the other door done then start on inside quarter panels. So far have interior roof side covered, one door interior (outter skin only) and just finished tailgate. So far, much better "sound" when you tap the body panels than with lizard skin alone. I purchased some dynamat extreme to go over the lizard skin before I saw the last few responses. A combination of different materials, like rubber on steel, will be most effective at blocking noise. 94635.html Horse stall mats would probably be better, but they are anchor heavy and not cheap.Īlso - material density boundaries reflect sound. I used the Harbor Freight floor tiles on the floor of my J20 - cheap and nice underfoot. Plain jute carpet padding is also very effective at damping and blocking sound. ![]() Maybe recycled coin flooring? The home stores sell rubber runner for stairways by the foot. I would consider and look for found materials like this for a while before I spent a lot of money on specialist materials. I would guess that old inner tube rubber glued to the surface would work just as well as fancy self-adhesive panels. Flexible material will deform and soak up energy to release as heat. More mass means lower resonant frequency. Sounds like it's just adding mass to the resonant surface. I would not use fatmat or any asphalt based alternative to Dynamat, they literally stink/smell in hot environments. It is much more effective, but I think the Lizard Skins is great for the wheel wells, under body, etc. The CLD tiles and Dynamat product work to absorb some frequency energy and turn it into heat energy. Lizard skins seems to work by changing the resonance frequency of the metal to a lower frequency that doesn't travel as far as the higher frequency. After a certain % of coverage, you won't notice much of a difference except for a lighter wallet. You really don't need 100% coverage with the Dynamat product to see big changes. I feel comfortable with result so will likely just move forward.Ĭheck out Resonix and CLD tiles as well. I cleaned it well and tested it and it is definitely stuck on there. I called Dynamat and talked to them and they said bedliner like finishes are one of the few surfaces that can present a challenge. I did buy two 12"x12" squares to test over lizard skin for adhesion. Thickness and cost are probably the only downsides I see and those aren't major reasons not to do it. I haven't been able to find reviews either, here or on other forums. The roof generates a ton of noise if its not coated already. Inside the doors is a must if you have not already coated the insides of them. So the bottom of the footwells would be a good place for it. You could just go and place it on the larger flat areas, which will transmit sound more than curved areas. But outside of having a thicker layer under the carpet, not sure I can think of any downsides.Īs a potential upside, you don't really need to put dyamat everywhere. I could not find any reviews of people using them together though. But dynamat can be more effort to install, provided the floor is also ready prepped. Lizard skin requires ceramic insulation to provide the thermal barrier. Dynamat is considered the better sound deadener, as well as acting as a thermal barrier.
