Thread: Fender protection?

Tweet

I'm thinking of applying heavy duty bed liner material on the underside of my 36's exposed fenders to protect from rock dings from the tires, has anyone had any experiences with this?

I've done it on a couple of vehicles now and it works great.

I use the 2 part urethane stuff you have to spray on that's called "xtreeme". It comes in colors and if you buy it in white you can tint it yourself by cuttting it with single stage urethane paint. The texture material (crushed rubber) is seperate and can be left out for a pretty smooth finish.

yup, done it a number of times and very satisfied with it! I use the Dupli-Color brand, put on with a roller, and two light coats.

Herculiner, comes in black, red, gray and white. Has a UV protector if you want it to stay bright.

I've had some bed liner on the undersides of my fenders for over 3 years - looks as good as the day I slopped it on. I believe that it was Dupli-Color, but spray can stuff, 2-3 coats worth. One caution - overspray does NOT come off like undercoating with a light solvent. You wait a few days to dry, then pick it off one speckle at a time (you really don't need to hear why I know that)

Check this out. Done in the 90's. Stomp my boots off on it. Looks like new every day.

Did my 38 and all my truck fenders we Herculiner works great and dose what it is suposed to.

I just repainted my '37, and part of the reason I did it was to repair several rock pecks on the fenders. I'm going to have to do something before I put it out on the road again. I'll probably do the roll on bedliner thing, but I was wondering if anyone has ever used a foam/rubber pad as a liner, like a high quality carpet pad?

Andy,
I haven't, but I wouldn't. Anything like a pad is going to trap moisture, and you'll likely rust out your fenders over time.

The rock stars in the paint can be an issue with my fiberglassed Cobra body. Many of the roadster builders use bed-liner to prevent that, and for the most part it seems to work good.
I used a product called EZ Liner that is also available in a spray bomb application. It drys quite hard, and I think for the best protection you would need several cans of it, to give it some cushioning from stones.

I wish now I had gone with their brush/roll on product that they sell. It could be applied much thicker.
products of the dominon sure seal

There is also a type of rock guard, that is like a sheet of flexible material, that you could stick to the inside fender wells. It is commonly used on later model production cars, I think to dampen road noise, more so than protection, (as most modern cars have plastic fender liners for that). Maybe check a dealer?

There is also an automotive aftermarket, self adhesive, butyl rubber material available. It comes in a box of several strips, that you just cut to length. They are about 6-8" wide, and 3' long. One fellow I know, used it on a Bronco he had restored, and he was very happy with it.

I have used SPI Bedliner under my Fenders-I like that you can set the Spray Gun (that they sell) to put it on as thick as you want, and, it's the kind of Bedliner that stays pliable (which I like)-you can tint it whatever Color you want (it comes with a Black Toner tube), and is a 2-part Product (meaning it sets up like Paint)-you can spray it with a Texture, or smooth-your choice.

I have used it on the Floorplans, underneath the Running Boards and Fenders-I like that it is durable, and looks good (at least to my old eyes)-my Car isn't done, so I can't tell you how well it lasts, but, like any other SPI product I beleive it is top-notch-

Does anyone know where I can purchase the flexible rock guard material similar to what you see in most newer vehicles?
