If you’ve been reading along like good little
minions dis-interested onlookers followers you know about the rust issues in the front floor pan of the Range Rover. You also may have read that I was looking for sound deadening products in my post back in September 2010, Shhhh! Last month I decided to do something about it….again. I purchased some Fat Mat sound deadener. I had two thoughts when installing it. It would…
- Reduce heat and sound
- Cover the floor pan
The reduction of heat and sound is a simple one. The Range Rover shipped new from the factory has a pad and carpet installed. If you pull that up you will find two small pads to reduce vibration and thus sound. The first thing you learn about the factory pad is IT IS A SPONGE. The second is it smells. And lastly it holds water and increases the rust chances for those metal surfaces.
The second to cover the floor pan, is simple, reduce water coming in contact with at least one side of the metal. I thought if I could coat the floor one more time and then cover it with this material I might minimize the rust. For certain, I won’t ever see rust there again as the Fat Mat material is very difficult to remove.
Once I began to prep the surface with grease and wax remover I noticed…the metal was already beginning to rust. Frustrated, I got the angle grinder out, too the surface down to bare metal. I then wiped the surfaces with the grease and wax remover and sprayed the surface with acid etching primer and after letting it set up. I covered the floor pan with pickup bed liner.
Over this I placed the Fat Mat.
All I can say about the install is follow the instructions. And put it on in small sheets. It would be impossible to cut the sheet correctly, peal the back, and get in place, and rolled down. As I type that I’m sure someone out there has done it or will do it.
I was careful to cover the floor in such a way as if water DID get in there it would not seep through the Fat Mat and sit on the metal. I know the floor will rust again, I just don’t want to see it.
Over the Fat Mat I placed the OEM floor pad and then reinstalled the carpet AND all the plastic trim! Yes! The floor project is complete.
Once I had completed this I also installed a Fat Mat bonnet kit as well. This was to reduce the sound as well. I got an added bonus light is reflected from its surface down into the engine bay.
The worst part of the bonnet install was leaning over the engine bay to wipe the surfaces and to place the mat.
After everything was done I took her out for a road test. I wish I had taken readings so I could have compared them. Over all I think it is quieter. I can safely say the heat in the leg area has been significantly reduced.
Over all I’d give the Fat Mat project a 1 (one) on the OkieRover Difficulty Scale
if you are just putting the stuff in sans rust abatement. I’d say this job was a 2 (two) if you have to grind any rust and spray any paint or surface covers.
Thanks for reading and Happy Rovering.
