View Full Version : Cleaning inner fender/ wheel wells that are DP-90 or flat black?

Mar 10th, 2013, 12:23 PM

I just has a general question regarding 1960's era cars with usual flat black inner fender/wheel wells. As we all know road grime/grease/oil/ even bug gutts will eventually 'spot' or degrade the look of a the flat black/ DP-90/ black satin finish.

Short of having some sort of clear on these, what products could one use to effectively clean these areas? I've tried various products which clean but you can still see an 'outline' of the previously effected area (almost like a water spot on a clear coat). Sometimes, depending on the contaminant, the black will even discolor (darker/ lighter).

This goes for the under neath of the hood as well and fire wall.

Many thanks for any product and/or technique guidance,

I usually spray with Super degreaser 4:1, scrub down/ hose off.
Use a leaf blower to dry wheel well and apply a coating of Griot's garage Undercarriage spray....works great

First I would just use regular car soap if that doesn't work the go with a degreaser. After your all done cleaning you should protect it. Hyper Dressing is my goto and if you want a nicer look then D156 Express Wax will do wonders.

I mix mine 2 Hyp:1 H2O to have a heavyer product. Most Detailers mix 1 hyp : 4 H2O to streatch product and have a lighter product.
That's a nice thing about HD is you can change what it looks like on a paticular applications ie: 1960's wheel wells
