Under fender rock ding protection?

[67rustavenger]

I don't know where to place this query! So here it is.

Summer 2019, I drove my 67 to my SIL and Daughters ranch a couple of times.
They live off the end of a paved road (2.5 miles) that transitions to gravel.
The gravel is like 2.5" minus.
I noticed later, while washing the grunge off the car. That there were small under fender dings that are standing proud of the basic fender profile on the outside of the fenders.

The family plan is to have me move to the ranch in the next couple of years.

I plan on using my 67 as my commuter car.
With the gas prices at elevated levels. Filling my Tundra's 38 gallon tank 2 times a week is cost prohibitive.

Onto the question, Does anyone make, or has anyone made an inner fender liner, somewhat like what we have on our newer modern cars?

I'm thinking of something like a hard nylon, black inner fender liner type of material, to prevent more rock dings from the gravel being thrown off the tires.

I have read a few threads on undercoating. But in my mind. Undercoating will not prevent the under fender rock dings from appearing.
Same thought process on "BedLiner." I don't see how it could prevent under fender dings from appearing on the outside of the fenders.

Any of you folks have a good idea to prevent under fender dings?

Thank you form putting up with my stupid question.

I’ve been thinking about the same thing too but more for rust protection. I’ve thought about a fiberglass overlay fender liner. I don’t think it’d work great on a beetle but on a more flat bus I’ve seen plastic corrugated sing board uses. Stuff like a yard campaign sign would use to put the information on.

Type 3s had a rock guard from the factory that was thick, it worked well at stopping rock chips but caused rust under seams. Here is a thread to look at https://www.thesamba.com/vw/forum/viewtopic.php?t=749897&highlight=rock+guard

Rhino Liner or similar spray-on bedliner. Easiest thing to do.

Made many of them when I was driving my bugs 80-100 miles a day with 22 of it being dirt roads and cow trails
I had a pattern from an old bug I parted out. Mostly I used old bathtub surround material which worked fairly well. I think I still have the old liner somewhere
Sure saved on the fender paint dimples
You don't need to do the whole fender only about the rear third or so

Does your car have aftermarket fenders by chance? I can't help but wonder if they're thinner metal than the originals and that's why they dented so easily? I only ask this because I've put tons of gravel road miles on Beetles over the years, and other than chipped paint, I never saw dents push through to the outside. I know that doesn't make a difference now- you still need a way to stop it from happening.
I do like the Rhino Liner idea. You could DIY that easily enough.
