Under Mudguard(Fender) Protection
I am trying to work out the best material to apply under the guards of the 540 roadster to help with protecting the fibreglass from star cracking as well as an acceptable finish.
On Harrision I used a urethane sealer/adhesive to attach 5mm high density foam under the guards, then applied about 4 coats of water based stone guard, then finished of with a couple of coats of 2 pack black. It looks good and appears work as a barrier for stones. The 540 roadster has lot more inner mudguard area to cover. Although I was going to use the same idea with the foam and stone guard I thought there might be a better way. I have been looking at the spray on ute liner material that companys like Rhino and Extreme do. This can be applied to any thickness that you require and is flexible and is touugh as nails. There is also a DIY option like Hippo Truckliner which also is a urethane paste based protective coating. Has anyone got any other ideas. Warren |
Hi Warren,
The chap that bought my Cobra has already had the underneath treated with Rhino Liner....reports that it's a MUST DO for my new Cobra..... Should protect against the dreaded Fiberglass spiders/stars that many of us have suffered over the years, and cuts down all the road noise It's included in the plan for the new car. Cheers, The "Other Warren " |
Hi Wazza, can you let us know what the stuffs called and where it comes from?
Regards. |
Hi Mando,
These are the companys that do spray on linings like what Wazza was talking about. http://www.xtremecoatings.com.au/uteliners.htm http://www.speedlineraustralia.com.au/index.html http://www.rhinolinings.com.au/ Warren |
Thanks Warren.

One thing to consider about spray on coatings is they
are difficult at best to remove if you have to repair a fender due to a mishap. I have been down that route and you need to get at the back side of the break as well as the front in order to do a proper repair that will withstand the test of time. Cracks are the biggest problem long term. The foam liners make this allot easier since they pretty much peel off whereas the Rhino coating must be ground off from the underside of the body.

try using neoprene. it is a thicker, more dense rubber. kind of like a wetsuit. i sell it here in the U.S. it comes with a sticky back. so cut to size , peel the backing off and stick to inner well. about 1/4 of an american inch in thickness. i am sure you guys down under can get this stuff too. if anything ..........cut up an old wetsuit. much better than that spray on stuff. just my .02 cents worth.

I approached Rhino liner here in newcastle NSW and the boss said it would cost me a carton of beer to do it. Then he told me to organise it with the salesman and that bloke decided... since it was a cobra it was going to cost $1600.00 bucks. I spoke to the bloke that applies it and he explained that the applicator gun needs a bit of room to manouver so it would be hard to apply even on an upturned shell. So I said no thanks.
I then found Speedliner and they agreed to sell me the product so I could do it myself. Their applicator man was on holidays so I emailed head office to confirm the application method and the Boss went crook and demanded I return the product and get them to do the job. So I e-mailed head office in Canada and they e-mailed a 14 page instruction manual. I used an old spray putty gun and got a pretty good finish. It's got a rubber feel and I think / hope I put it on thick enough. Not a fun job but worth it (I hope). At least I've got a pair of pants that won't wear out in a hurry. |
I sprayed the Stone Guard stuff on with their special applicator gun and my compressor. Messy business but it is tough! I have also glued a setion of rubber sheeting up under each 'guard.
I had the back of my Nissan Navara ute sprayed with a new product that has a 'lifetime'warranty and that only cost $700! It is really good at stopping abrasions and scratches but I am not sure about its impact absorption qualities. Merv |
Hi Merv,
I did the same as you on my Harrison, looks good and appears to aborb the hits from stones. What glue did you use to stick the rubber on? Warren |
That sounds good. I used a high temp Selleys adhesive with Sikaflex 252 (?) on the edges.

Have any RMC owners had the problem with star cracks appearing on the outer paint job above the wheels ? The body work is pretty thick and I think it would take a mighty big stone to do damage through the f/glass. Can any one tell me if this happens to the RMC ?

What are the requirements for registration and safety certificates when it comes to inner guards, are the glued on neoprene or spray on rubber rhino ute stuff acceptable in Queensland. It sounds to me that a 5mm neoprene rubber stuck onto the inner guard would be sufficient and i probably wouldnt go through the expense and trouble spraying the rubber stuff on, just my thoughts.
Cheers Damo. |
Damo, there is no requirement for any under guard treatment for registration in QLD. It is a purely to reduce sound of debris inside the wheel wheels and also to reduce the chance of damage to the body.

Merv, what sort of rubber sheeting did you use? I got a quote from a local Neoprene supplier and they want $130 for a 125mm x 3.2m sheet in 5mm thickness. I reckon I'll need $400 worth at that rate! Does anyone have a cheaper option? I plan on sticking it to the wheel arches and applying body deadener over the top. Nothing fancy. |

I used a product called Raptor made by Upol.
It is a ute bed liner and available from most local auto paint outlets. I got it from All Paints in Glenroy Ph 03 93004133 and cost around $140 for 4 litres. It comes in black or tintable to your colour choice. http://www.u-pol.com/countries/en/do...tor%20tint.pdf http://www.clubcobra.com/photopost/d...03_Medium_.JPG |
Great finish there 'Dale. I'm looking for a little more than a thin coating in the wheel arches though. The Harrison body moulds are pretty thin. I've sourced 5mm x 127cm x 325cm neoprene for under $100 down in Scoresby and that should do the trick. Next stop... what adhesive to use? Sikaflex might be overkill for the whole job.
