Trying to reduce road noise
 
One of the first negative things I noticed about the Focus, is the somewhat loud tire/road noise on medium to course surfaced roads. I have already treated the doors with sound deadening treatments with good results. A noticeable reduction in overall road noise was achieved. The noise from the tires touching the road was still kinda loud. I thought about this for some time now and realized that if the noise is coming from the wheels, then cut the noise at the source. The front fenders have a thin plastic inner fender that is the first defense against tire noise. I decided to get some rubberized undercoat spray, it says for sound deadening right on the can! I easily removed the inner fender wells with a few plastic fasteners and sprayed on a few coats inside and out. It took 3 cans @ $3.75 each to give good coverage. I think 2 cans per fender would have been better, but Kragen only had 3 left. If this gives the result I would like I may use it in many other areas especially under the cargo area which has some factory undercoat but many areas are still bare. I'll test it out tomorrow and report on the results.

An easy improvement will be different tires. The Firestones that came with my ZX5 were noisy. My Bridgestone RE750, besides being a better tire are much quieter.

I have the original Goodyear Eagle RS-A's. How are they noise-wise?

Quieter than my old Firestones, but not as quiet as my Bridgestones.

Tires will be replaced when they wear out, 19k on them and the tread is still very deep.

Do you have cloth or leather? Cloth is a little quiter (it asorbs sound).
Try pulling the small panels on each side of the foot wells and putting padding their.
You can also get the stick on sound deadening material at a store that sell paint to body shops.

I have cloth seats. I've stuffed the trim panels with foam tape and plan to do a lot more. Thanks

Are these the 18oz. aerosol cans? If so, here is a cheaper option at $1.99/can

They are 18oz cans made by Bondo. That price link is almost half of what I paid, but with shipping and the wait, I don't think I did too bad for a spur of the moment decision. If I do any other areas, I'll definitely look for a better local deal or cheaper alternative, because one can doesn't go very far. Actually Kragen's online parts store is Partsamerica.

Here are one gallon or five gallon options, expensive stuff, but thick:
