liner for inside fender wells?, what does eveyone use Options

[stugray]

I am considering putting something inside my fender wells to protect from rocks "starring" the paint from the underside.

What does everyone else use?

I am thinking of glueing neoprene sheets (like a mousepad) to the underside of the fender with contact cement.
I have 12" X12" squares instead of large sheets.
So if one ever comes loose on the track, a small piece would not be a hazard.

I think the neoprene sheets would be lighter than a thick coating of spray undercoating or bedliner.

Next - anyone who has done this, how much of the fender is at risk?

You must be stalking me. I just put the finishing touches on these today.
Pics will follow tonight.
Don't glue the closed sell foam in there, it will trap water, just like the mud and dirt you are trying to keep out.
I think you will like the solution I have finally got worked out.

Closed cell foam does not absorb water, so it won't trap it. Depending on how you glue it, if there are voids, it could get trapped in there. If you are worried, you could use open cell foam and then it would hold water, but you would be able to squish it to get the bulk out and then it would air dry.
