Lizard Skin Sound deadening spray

[Alex_V]

What are the thoughts on Lizard Skin Sound Deadening coating? Right now all my bare metal panels are coated with rubberized spray. My plan was to add Summit Racing heat / sound mats in the cockpit, and rubberized spray inside of the shell.

Got a free 2 gallon bucket of Lizard Skin sound deadening coating from a friend yesterday. Now I am thinking to perhaps use that on the inside of the shell, or coat the cockpit and then a coat of Lizard Skin heat coat.

Any thoughts?

I like Lizard Skin, and used both their heat and sound insulation on my build. It's a lot of prep work but I like that it seals up all the *small* gaps (it will not seal up larger gaps - work still needs to be done to close some of those up before spraying Lizard Skin). However, you said you've already coated all your bare panels with rubberized spray. Are you suggesting applying the Lizard Skin over the rubberized spray? Not sure how that would work out.

I too like Lizard Skin and have used it on every build. Both the sound and thermal products on each. Agree the prep work takes awhile but it sprays out quickly and in my experience does what it's supposed to. Don't underestimate the amount of overspray and where it goes though. I do mine outside on the driveway on a tarp. The total amount of time is similar to fitting, cutting, and pasting stick-on products. Have done that too. I wouldn't bother putting it on the underside of the body. Frankly I don't see any advantage of anything on the underside of the body other than some type of undercoat to give it a uniform look plus extra coats in the wheel wells for protection. The main advantage of the Lizard Skin IMO would be on the inside of the cockpit and if you're so inclined the trunk area. Not everyone will agree with that... I also agree I'd do an adhesion test on the rubberized spray you've already applied. At the very least, probably needs to be roughed up some. FWIW, this is a write-up I did on Lizard Skin now some years ago. Many have commented it was useful for them. https://www.ffcars.com/threads/lizard-skin-application-experience.342954/

I use lizard skin sound deadener and ceramic heat shield on all my builds with great success. :cool:

I followed Edwardb's write-up that he's linked above as closely as possible, and was very happy with how mine turned out. I also agree that's it's MESSY. I thought I'd masked off pretty well, including setting up a spray booth of sorts using Zip Wall poles, but still got overspray on the floor, the posts of the lift, the compressed air hose, inside of the garage door, and all sorts of other places I didn't want it to go. Either spray somewhere where overspray won't matter, or put down a lot of protection.

That is some serious masking work. My vision was of something being more simple. I guess it is not.

You really do want to spend the time prepping and masking to get the best possible outcome. I spent several days sanding everything that was going to get sprayed with 60 grit, then wiping down with acetone, then sealing all gaps with Dynatron seam sealer (or epoxy on some of the bigger gaps). Then probably a full day masking everything. The spraying goes pretty quickly. Each coat only take a half hour or so, with a couple of hours between coats. Then repeat the next day if also doing the heat insulation. As I mentioned in my build thread, it definitely took me a lot longer than I anticipated, but I'm happy with the results. As with most things, the more prep time you put in, the better result you'll get.
