lizard skin vs upol

[RaserX]

I was reading up on the Lizard skin sound deadener and ceramic heat shield spray on liner. In my reading I found that the Lizard skin will reduce temps by about 30 degree's as well as deaden the road noises. Only it does not stand up well to oil and depending on which post you read heat is not that much of an issue in passenger compartment. I also read up on the stick on types of deadener each having their own positives and negatives. I did the same basic reading about upol raptor spray liner for the underside of the body to protect from rock and such.

It occurred to me that the upol spray liner would accomplish the same basic function as each of the other types of linings but have a tougher endurance as well as cheaper cost for some thing you will not see after the interior is finished.

Has anybody used the upol as the interior lining?

Do you see any negatives to using it?

Is heat protection really needed in footwells in Ohio?

Any comments or suggestions appreciated

Check out Edwardb's build threads.

I've only used the UPOL Raptor on the backside of my body, but he's used both products Lizzard Skin on the aluminum floorboards and UPOL Raptor on the back of the fiberglass parts to protect them.

I've used them both. UPOL Raptor and Lizard Skin are totally different products. Lizard Skin specifically for sound and thermal properties (two different products, typically applied on top of each other) and Raptor specifically for surface protection. Lizard Skin is a latex product that cures via evaporation. Hence night quite as durable. While Raptor is a catalyzed urethane that's significantly harder and more durable. While Raptor probably has some level of sound or thermal properties, that's not its purpose and I personally wouldn't use for that purpose. Under carpet, the Lizard Skin has no durability issues whatsoever. Some do leave it exposed. I've heard of some applying it on the underside or in the engine compartment. I personally wouldn't do it because it would be hard to maintain and keep clean looking. But I wouldn't expect heat or most automotive products (oil, whatever) to break it down. Yes you want heat (and sound) protection in the footwells. And the entire cockpit IMO. Doesn't matter where you live. At least for a street driven car that you want to be comfortable in.

Thanks Guys, Does spraying the trunk make a noticeable difference?

I don't know. Probably overkill, but I've always sprayed it. So nothing to compare it to. Although probably not as thick as in the cockpit where I try to maximize as much as possible. But easy enough to mask the trunk along with everything else and spraying goes really fast. Your choice.

I didn’t see any advantage to applying Lizard Skin until now. I didn’t want to set up for spraying and thought it a hassle where I could just cut, peel and stick the Thermo-Tec product. I didn’t realize it was super fast to apply and the stick on sound and heat mat material is very time consuming. Paul, do you know the weight of the Lizard Skin you applied? I can say for certain the Thermo-Tec is 40 pounds just for the complete cockpit area.

For each of my builds, I've used (2) gallons LizardSkin 50100 Ceramic Thermal Insulation at 12.5 lbs shipping weight, and (2) gallons LizardSkin 50115 Sound Control at 38.5 lbs shipping weight. That's for Roadsters and includes coating the trunk area. That includes the container (plastic so not very heavy), just a little left over when done, plus some amount of overspray. So, I would say best estimate about 30 lbs added.

FYI, for the Coupe sprayed the cockpit plus hatch area also using two (2) gallon buckets. But for that build I did use some stick-on in the footboxes. Overall there's more to cover in the Coupe than in a Roadster. So probably around the 40 lb mark for the Coupe.
