wheel arch liner

Could anyone out there give me some advice,i have just washed the arches after removing the liners and could see no rust but plenty of dirt in corners,so the question is are the liners best left off so normal conditions dry out the water or do you replace them risking damp and dirt building up again .Any help would be gratefully received.Glyn

Put them back on again, you will get more dirt collecting there without them being on.

I agree with the above, and the car would look weird without them.

Mine has no liners, and while the under arches do get muddy it looks fine. It took me a while to realise there were no liners when I got it.

Three years later and no problems yet.

Thanks for the input everyone ,but i am still not sure what to do maybe a few more answers will help me decide
