I removed my front guards and added some Silicone to the bottom inside where it had some play infront of the side FX.

I fear that with the coming snow the slush and ice hitting the guard while driving would possibly mess up the side FX skirt.

This made it solid and removed the little play there was in the lower part of the guard.

I had planned on putting another screw in lower but the lower effect is just plastic and you will not get a very solid mount.

The silicone is removable too if you should ever some reason need remove the guard.

It ends up working as a space filler gasket and glue in one.

 

Good idea . . . I have moulded splash guards on my 2500 HD, and they have worn through the paint on the wheel flare . . . . . . .

 

Good idea
Thinking about doing that on mine, i have available , some nice silicone inna can at work that is more adhesive than silicone (holds better than straight silcone) that i might try.
Since everything else i've driven in winter tends to be a catch-all for slush/ice/snow after driving in my area, it's prob a good idea to beef up the guards since the mounting is kinda flimsy
Will try it out when i pull mine in the garage for it's tire rotation (which it's way due )Since it comes in a pressurized can , i can apply it 'tween the guard and the car and get a good bead applied and remove excess ,leaving a minimal amount to do it's job since like i said this stuff bonds real well. (but still can be removed if/when the time comes to do so.)

 

Also on the rear flaps I used the clips from a screen door that retain the window in the door to hold the bottom hole.

I used a stainless bolt, nut and washer to help clamp it to the lower fender and give it some more support.

As for the silicone you want some stick but don't glue it on too hard as if you need to remove it it may be a problems on the rocker.
