My new warn rock sliders are lookin pretty sweet on my TJ. I did notice though, that they don't fit completely flush with the body on the side. There are a couple of gaps along the length between the guard and the body. Is it a good idea to run a bead of silicone down the slider to fill in those gaps to prevent road salt and grime from getting down in there? Or is it going to keep it from drying out since road grime can conceivably still get in there on the bottom side? It's still going to be open on the bottom behind the slider since i don't think i could get in there behind it to run another bead of silicone. I'd appreciate any thoughts on this.
