Invisible Undercarriage

[pirahnah3]

So I got a bottle of this in a recent mystery box and having watched the vid in the past (what a beautiful F40!) I went back and watched it again. So I kinda have the general idea of how to use the product. Now my question comes in after thinking about it. 

 

The fender wells in my 2015 F250 are more of that felt type rather than all plastic. They have that nice matte black look to them already,

 

So two questions off of that,

 

1. Is this product safe for those felt type panels? I am hoping to increase tire size to fill in the wheel well a bet when I need to replace them early next year most likely. 

 

2. What other uses might there be for this product?

I generally just clean the felt with either a soap mix or APC and scrub them out, normally don't do anything else to them. For my truck I hit the frame/suspension components I can reach with IUC spray. Doesn't last as long on metal surafaces but it sure does look good. If I remember correctly IUC is somewhat flammable so it was recommended to use sparingly if at all in the engine compartment.

Don't use it on the felt.

Don't.

Do NOT use it on the felt or fabric tire wells.

 

Those you just have to brush out and rinse (apc isn't really needed there anyway) - my buddy used a rubber pet hair brush on it actually and it works real well to loosen the crap up

Yet another use for a pet hair brush in the detailing world! I use one for my old wash pads. Might have to give it a try on the fenders too (this is my first vehicle with felt fender liners).

Yeah my X5 doesn't have them but my wife's has them in the rear only (random) her car sits pretty low so I actually haven't needed the spray on her front wells just clean and brush the grime away, you can barely see them (2014 Jetta Sportwagen TDI)

Thanks guys, looks like this one might be heading to the Trade section.

Hmmm, how can I best tell what my wheel well is made of? I've already sprayed it underneath the wheel wells.

Reach in and feel it.

Why is IUC not recommended for felt wheel liners?

most cars have plastic, some have felt and it looks like a low pile carpeting, some are all black while others a grey with black.

Because it isn't designed for felt wheel liners.

Undercarriage Spray works best on smooth surfaces. The felt surface is too rough.

Well this was super-helpful and timely.  My new car has fabric wheel wells (something I never even new was a thing).  I found this out when I was about to go at it with the Undercarriage Spray as I did on my Camaro.  Ended up skipping it and just spraying it down.  Checked here for advice and here y'all are.  Thanks!

 

Now to Petsmart for auto detailing tools
