My $67 sound dampening / undercoating
I have been meaning to paint the inside of the wheel wells since I bought my Yaris to get rid of the patchy look of some visible paint and some patches of seam sealer.
This Saturday I was planning on doing an oil change and figured I would do something with the wheel wells while I had it up on the lift. Doing a little research on coatings for the wheel wells, I found that Herculiner paint-on truck bed coating seemed to be a good choice. It is a urethane rubber based coating and is promoted as being for both truck bed protection and undercoating. For $67 for a gallon, I figured it was worth a shot. I wanted something that could be brushed on to avoid the mess of overspray. Herculiner.jpg I initially applied two coats to the wheel wells. I then got under the car and coated the floor pan. This morning it was done curing, so I took it out for a test run. The roads were wet and coated with sand from Saturday's snow storm. I was extremely impressed with the sound dampening that the coating provided. Yaris - Undercoating.jpg Yaris - Undercoating2.jpg Yaris - Undercoating3.jpg

nice! I went with the more traditional fatmat at 1$/sq foot lol. I used only 50ft out of the 100 i bought, but plan on using a weee bit more when it warms up for the extremely noisy engine.

Negligible as compared with something like dynamat. An entire gallon weighs about 10 lbs and I only used about 1/3 of the gallon. I think I have enough left to do Crashy and my Tacoma.

Even if it weighed 50 lbs, it would have a negligible effect on...well, anything! I plan to do something like this soon, the road noise is bad on these cars. Thank God the engine is fairly quiet at speed.
Good job! I never thought of bed coating... It dries very hard then?

Very nice - I'd love to do some sound deadening work at some point. It would be interesting to see someone do a before and after sound level test. I wonder what fixes have the most payoff.

Deathegg - The Herculiner cures firm but flexible. It is urethane and is probably about half the durometer of roller blade wheels.
Josh044 - On Sunday night I was watching Wheeler-Dealers and they bought an old pickup to resell. The thing was loud as could be, so they bought a sound insulation kit for it. Before and after they did a sound level test and I sat there watching it going - Dang, I should have done that. I even have a good sound meter app for the iPhone.

Looks like $67 well spent. Did you have to pressure wash the dirt out before applying or just slapped it on?
Also curious about how much sound it helped block out. Damn your iPhone and that hindsight of yours! heehee. |

I pressure washed it with Simple Green (and vacuumed all of the pebbles out of the leading edge of the rear wheel wells) before painting it.

I can just barely feel the difference when I pull my sub box + amp out... and it's pushing 90lbs. CTScott, do you have any vids of your mufflerless exhaust? Just wondering how it sounds.
