Under body/ fender rubber coatings?

[Drakman]

Hi Guys and Girls,

 

I am looking for a product that can be applied under the rear fenders/guards/mud guards, whatever the correct terminology is, that will prevent stone strikes from crazing the paint on the outside of the fenders.  I would assume there are rubberized coatings? that can be sprayed to the under side of the fender to help absorb the energy of small rocks/stones.

 

Thanks 

Dave

You mean like paint on truck bedliner (or to use the Australian - ute tray liner)?

 

LineX  is one brand but there are many other brands out there with the same purpose.

Bedliners | LINE-X (linex.com)

 

LineX is applied professionally but there are equivalent products that are designed for self-application.  Look for Raptor Liner, Rustoleum, Duplicolor.  I recall seeing the first two brands in Sydney over Christmas when I was there.  

 

Another alternative is Plasti-dip paint.  Not sure how durable it would be in that application though.

 

Only downside to consider is that the spray on applications add a bit of weight.

Can't say I've ever used a spray on bed liner for anything but under the fender wells of my Cobras, but adapting the same for the "7" will work equally as well.

 

Rustoleum spray on bedliner in a can, I use 4 cans for the wheelwells and floorpans (sprayed under the car only) on my Cobras. Available at most autoparts stores. Follow the instructions, use only in a well ventilated area, and use eye protection.

It seems the best protection is hard bed liner with rubberized "undercoat" top coat.

cut a sheet of plastic to wrap around the inside arches as a barrier.  secure it with bolts from the brake lamps and re- rivet the top line of stone guard rivets, or use screws.

perhaps a sacrificial black trash can will give the pieces you need. And its removable.

Add drain holes.

I've used brush on rubberized truck bed liner and it's done a great job even considering that I autocross the car with very sticky slicks about 20 days a year. I've used Herculiner and was able to pick up a smallish can at my local Ace hardware.

 

I've used it on the underside of both fiberglass and carbon fenders and never got any cracking even with all the junk thrown up by the slicks. I've used 3 coats. One nice side benefit is that it makes driving a bit quieter with stones hitting rubbery stuff instead of a hard surface.

Thank you all for the responses,  I would never have thought of "Ute tray liner".   Time to do a bit of research now.

 

I nearly jumped out of my skin the first time  a stone hit the underside of the rear guard, it was so loud, i was expecting to find the guard in pieces.

 

Thanks

I had all four wings coated with LineX by the local dealer.  Had to "de-mount" the wings but not really a big problem.  I was told by the LineX dealer that all of the "Big Rigs" that run fiberglass fenders have them coated.  It has served me well ever since it was done in 2009.  Didn't help with the fender the bear hit in 2013, but the others have held up well.  Of course, some of the racers asked if I knew how much weight that added to the Seven!

Thanks Guys, I am only looking at doing the rears at the moment, the front wings are some kind of plastic so i think they might be a bit more resistant to crazing the paintwork.
