my car has done 3 miles and already the rear arches are cracking from stones battering the insides
what can i use to stop this
thank you

Carlife Rubbercoat or maybe Wunderseal from CBS??

Wunderseal

I've used the rubbercoat (took a week to cure fully when i used it!!) and didnt have any star cracks on my arches at all in several years of use

sounds like the stuff i need altho i might order another set of arches first

I went for the belt and braces approch. I put some CBS soundmat under the wings and then painted over it with wunderseal.

I'm just accepting it as part of the inevitable wear and tear on the vehicle, and that some body panels will need replacing eventually/before I sell it to freshen it up.

The star cracks are tensile --- main line of defence is to put a extra layer or two of woven mat on the inside, then underseal.
