Rock impact damage to dually fenders.

[steamin53]

Getting a lot of star shaped cracks in the top of the fiberglass dually fenders on my 94 C-3500. Strange to me that they didn't think to put any rock shield liners in these fenders.... F*rd did!! Anyone know of an aftermarket source for liners for these fenders or perhaps some other solution. Seems worse on the passenger side...guess that makes sense sense that's where most rocks would lie on the roadway. Body shop says he can patch but it won't last so probably should replace the fender. Anyone know of a source for a good but inexpensive fender? Steve

steve, they can be fixed but it is costly like everything else..

I have taken Plastic Roof cement ,5 $ a gallon at the local home improvement store and applied it to the under side of those fenders before..It keeps the stars-cracks away..The surface must be clean to apply..Just use a putty knife and some gloves and smear the stuff on..

My 1/2 cent.......

^....I'd look for a replacement from the scrap yard and spray it with Line-X bed liner.

I sprayed minewith urithane (spelling) foam, it works great and I do gravel at high speeds every day.

I have a couple of Hot Rods, '39 Chevy and '66 Chevelle. Now with a $10K paint job, you can't afford to have sone chips on the front or underneath the fenders (you know those #@^&%%$# star shaped things).

So here's what a lot of us Hot Rodders do....

Go to an upholstery supply store and buy a couple of yards of a product called "Closed Cell Foam". It comes in several different thicknesses and you can decide how thick you want to work with. Cut this stuff with sissors or a box cutter (bad day to use that word)to fit the inside of the fenders. Get a tube of liquid nails and your caulking gun, lay on a few beads of the liquid nails, then stick on the "Closed Cell Foam" to cover the inside of the fenders.

Now it is extremely important to use only "Closed Cell Foam" since this stuff is not porous and will not let water get behind it leading to rust and having the stuff fall down. Mine has been on my inside fenders for over 10 years now and it's dirty, but not torn or loose.

Takes a few hours, but really works and it is very lightweight. Kind of like gluing up a carpet pad, but easier.

Anyway, might be something simpler, but this stuff works great, it absorbs the hits and I have never had a star hit yet on the '39 or the Chevelle.

Good Luck

Thanks for your tips guys...hadn't considered using foam or roofing cement...did consider undercoating material. BEARMAN, I took a look at your pics on the web. How do you get away with towing tandem like that with the trailer and boat? Do you have brakes on the boat? I thought that was illegal but could benefit from doing it if it's not.
