My $67 sound dampening / undercoating - Page 3 - Toyota Yaris Forums

^^^^^ Oops

. I just read your other posts (and other's posts) on this thread and realize the difference you are referring to = in performance not MPG. Amazingly faulty assumption on my part, especially since you are 'Mr. 143'. Re my Yaris, I am probably too clouded by MPG as a first thought.

I just thought (not based on more than a vague hunch really) removing it wouldn't make any difference. I trust your judgement. I don't think you would write this unless you had noticed a difference (even if it isn't much). Come to think of it, I can't remember the last time I had to put the spare to use in a car.

Took 3 gallons for 2 thick coats on my LC

I just realized that it has been a year since I undercoated it. Since Crashy and my 09 are in opposite spots in the garage in preparation for the impending blizzard, I put the 09 on the lift to see how the Herculiner is surviving. Not a bit has flaked off, even with the wicked road salt around here.

I applied the herculiner undercoating today to my wheel wells! I couldn't apply a second coat due to time constraints and being called into work :( I figured a little dust couldn't hurt and I'll just apply the second coat tomorrow or Wed. Did you do the entire floor pan of your Yaris? I'll try to do the floor pan by next Sunday hopefully. I learned today to buy a paint projector respirator - this stuff made me dizzy and lasted until the middle of my shift tonight >.>

I did do the entire floor pan, and on Crashy2, when I had her gas tank down (to weld the inserts to the floor for the 60/40 rear seat conversion) I even did the area above where the gas tank sits.

You definitely want a good chemical, as opposed to dust, respirator, as the fumes are really bad for you to breathe.

I swung by home depot for a professional respirator this morning - I'll be up close and personal underneath my car this coming weekend. I didn't notice too much of a difference today while driving my car. I think adding the second coat to the wheel wells and starting the floor pan will be noticeably different *crosses fingers*

How well this structure keeps on metal?
Whether will be with corrosion time under it?

It bonds very well to the painted metal. It is made for coating the bed of a truck to protect the paint and prevent corrosion from abrasion.

The body should be washed from a dust before drawing?

Yes. Washed very well to remove any dirt, salt and oils and dried completely before applying.

This is a great idea - I thought about getting some kind of undercoating to do the rear wheel wells as part of them were missed (bare metal) from the factory.

Autozone has a smaller 2.5 pound can of the same stuff for $29.99, in case folks want a smaller can to do just the wheel wells. Will give it a go one day and try a 2'' or 3'' throw-away brush. - Again, this is a great idea, thanks Scott

The little can is probably enough to do a couple of coats on the wheel wells and a full single coat of the bottom. Just make sure you either apply it outside or wear a respirator. The fumes during application are nasty and dangerous.

I did this using roof asphalt coating paint. I only painted the half of the wheel wells that is on the passenger cabin side (the car was undercoated from the dealer).

I also attached patches of rubber insulation foam before coating.

It doesn't reduce the road noise that much, but it does noticeably shift the noise's frequency lower.
I also have done soundproofing using weatherstrip rubber on the B-pillars, and rubber insulation foam in the cavities in front of the doors, and underside of the doors.
The noise became less irritating and I can have a conversation in car clearly up to 80 MPH -- where wind noise is starting to have more effect.
