Undercoating Your Inner Wheel Wells - How To ! - Toyota Yaris Forums

*Chris07LB* · 07-11-2006, 07:06 PM

One of the things that bug's me about our cars, is the very noticable exterior color overspray in the inner wheel wells.
Now maybe because I own a Polar White, its a little more noticable then other exterior colors, but all the same, it needed fixing.

One can was enough to do all four wheel wells, and there was no need for heavy or second coats. One pass covers very well, and the spray of the coating was very easy to control.

I took my time, and removed one wheel at a time, being careful not to Undercoat any brake lines, plastics, springs, shocks, etc. Again, the control from this can's nozzel made the job very easy to get in and around tight areas.

Starting with the front drivers side.. BEFORE

Lots of overspray as you can see, and just ugly when looking at a side profile of the car IMO.

Cleaned the area up well, and Undercoated the front.. AFTER

Ah, much better!

Now moving onto the rear.. Before & After

I am letting the Undercoating "cure" overnight, as I did not need to drive it after I did everything today.
If you can go 12 hours, you should be fine. It was still a bit tacky after about 2 hours, and I didnt want to risk kicking up road grime, and having it stick to the fresh surface.

what happen to the picture?

TRD_Yaris · 07-11-2006, 10:49 PM

i think he's still busy adding them. Uploading pics and doing a DIY write up are a pain in the arse.
i'm anxious to see the results..it should reduce road noise JUST A bit.

El Jefe · 07-12-2006, 01:59 AM

so what brand of stuff did you use? i plan on doing this sometime, i bet it looks really bad when you have big wheels that you can see through

03Z33 · 07-12-2006, 02:53 AM

Or you could just lower the car to get rid of the wheel gap

*Chris07LB* · 07-12-2006, 06:03 AM

YOU CANT SEE THE PICTURES???

They have been up and working since i posted.

Works fine for me.

*Chris07LB* · 07-12-2006, 09:28 AM

johnnyfive · 07-12-2006, 10:18 AM

TC-LIFTBACK · 07-12-2006, 10:42 AM

That's a great writeup. I'll do that at the same time I coat my calipers and drums.

Thanks Chris!

*Chris07LB* · 07-12-2006, 10:46 AM

You're Welcome.

Glad to see some excitement over the "little things."

I though most would deem it a complete and total waste of time.

JDMVitz · 07-12-2006, 02:04 PM

Thanks for the article! Looking forward to your spring install!

NOPE. Looks great. I was thinking of it, but I haven't had the time lately. I've been busy at work and at home, so I'm not on here much any more, just about once or twice a week. I was thinking of doing this, but now that I see it I'm motivated to get it done sooner!! Great work.

Moose · 07-12-2006, 06:48 PM

Awesome! I live on a dirt road and also drive a whitey, so this may be well worth it, especially if/when the aftermarket wheels get slapped on.

Moose · 07-15-2006, 03:36 PM

Well, I pulled my wheels off the other day to prep the area to do this, and it's already done!

Maybe the sedan comes with the coating stock whereas the LB doesn't? I dunno, but I'm not complaining.

hhcchen · 07-15-2006, 04:08 PM

for those cars that's been done...
could it be that it's just sedans...?
or does it include liftbacks with more options on...?
or could it be part of the winter area package...?

I have Cold Weather Package a.k.a. Winter Package, if they are indeed the same thing?

Either way, compare the pics above, and the choice is clear.

BTW - you could just use Black Exterior spray paint as well.

yeah, but the black paint is not going to stand up against the constant barrage like the rubberized undercoating. plus, this should sound insulate the wheel wells just a bit more, if you consider that an improvemnt (c'mon! i love the sounds of rocks hitting my fender liners!!)

... It was just another option for those looking to change the look.. Black paint is good, Undercoating is better.
