Attention: TDR Forum Junkies 
These guys have diamond plate rockers for Dodges. Interesting looking. 
rockerpanel mouldings on my 02 w2500 and the d@mn things are already starting to rust!! A friend of mine also has a set that started to rust and I replaced them with another set from the same company but of a "better" grade (304). I was going to replace mine also but after only 2 weeks on his truck, they also started to show the same rust specs on them. We called the company and all they had to say in thier defence was something about the recent snow storm we had and the amount of salt our country uses. 
Doesn`t stainless mean they won`t rust?? Just my 2 cents on what brand I would stay away from. . The product in my eyes, could sure be improved!!
I inquired about having the Line-X sprayed on the qtr panels when I had the bed done. The quote was $800 big ones:--) When I asked how come so much, the reply was that they would have to tape everything off underneath as well as above. It would look nice and would probably help with sound deadning some what. 
. I have no idea what brand they were as they were on the truck when I bought them, but they would get small rust spots just like the guys above mentioned - and it took forever to polish them up. I gave up on them and had the rockers sprayed with Permatech bed liner material. Here's a repost of an old post I put up about it:I picked up my truck yesterday after it's surgery last week (I hit a deer a couple of weeks ago). Since they had to work on the rockers anyways I had the body shop fix any corrosion I had from paint chips (hundreds of them) and then had the local Permatech dealer spray from the body line down in a dark grey that is matched to the dark grey on the front bumper (VERY close match in color - not quite exact) and all of the exposed metal inside of the wheelwells in black. I had them spray all the way around the pinch welds on the bottom and all. Also once the fenderliners were removed (for spraying) I found that on BOTH sides of the truck in the front wheel wells toward the front that the liners had worn through the paint in an area about 2 inches in diameter and there was a lot of corrosion there - I had the body shop remove that corrosion too and had the liner place spray a very thin coat of the liner over that area so that it doesn't come back. Any of you guys that plan on keeping your truck for a long time may want to remove those front liners and fix that spot before it rots out the fender from the inside. From the side of the truck you can't even tell unless you look REALLY closely that the inside of the wheel wells is coated, looking straight down from the top of the truck it sticks out about 1/2 a millimeter is all - but that's enough that rocks won't be able to chip it! The body shop was extremely impressed and the manager there is going to have his truck done now too he liked it so much. Now I won't have to spend 20-30 minutes a month repairing chips around the wheel wells, pinch welds, and rockers!! WOOHOOO#ad
BTW, I haven't had to fix a SINGLE rock chip since last January when I had it done. A few things to consider, check out the installing dealer very carefully - ask for references on a couple of trucks that you can look at yourself to see how good of a job they did (the installer means more than the material used IMO). Next, make sure they know EXACTLY what you (where you want sprayed and where you don't) - my recommendation is to arrange to be at the shop when they are masking it off so it goes right the 1st time. Lastly, pick your color carefully. AFAIK permatech is the only manufacturer that mixes the entire material to the color that is to be sprayed. Others just paint over the top of their standard color - the difference there is if the surface get's gouged the solid one won't show, whereas the coated one will. Also, I'd recommend you make it two tone rather than trying to have one solid color from top to bottom. LSFARM had his rockers sprayed at the same shop I had mine done at but had them try to color match his intense blue paint job. Their first try was too light, they got very close on the second try - HOWEVER, it all depends on the lighting. Depending on the angle and the lighting it can look EXACTLY right or off by quite a bit - hard to explain. In my case I had them spray a darker grey that matches the lower bumper fascia so the color match didn't match as much (expecially since the driftwood rockers originally were WAY lighter than the bumper fascia - it's MUCH closer now). BTW, price was around $400 for LSFARM's application I believe.
