Shock,
I would tend to agree ALMOST 100%. Being VERY well versed in body work for 30+ years and an avid detailing enthusiast, modern plastics are NOT the same as paint! However, The UV coating on some lenses and in this case RAMS, isn't quite the same as, say, the coating the lab at the eyeglass place puts on new eyeglasses. It seems this stuff was MEANT to wear off! Case-in-point; my headlight lenses are actually peeling/deteriorating visibly. You have to get up close and personal to see it, but, it is wearing off...not just fading or yellowing. And nothing has been done as far as restoration at this point to cause the wear. I have even waxed all lenses several times per year with the rest of the truck (a fettish I suppose). Evidence is povided by the fact that the corner lenses are clear as can be. Granted, they do NOT have anywhere near the heat in them as the headlights.
I guess the point of all this is that once that coating is compromised, the lense is toast! Whether the compromise is from natural conditions or Pointdexter (lol) the damage is done. So what choice do you have? Replace the lense or try to polish it. Even if that means you must polish every few months. I think you'd have to admit you can buy a lot of polish and buffer pads for the $200 that they are asking for replacement lenses. I guess I'll just keep polishing periodically for a while longer.
BTW did you see the one about the brake fluid? I'll just leave it at that.
Great info though for the otherwise unenlightend.
One final thought...nowhere in the Ram Owner's Manual does it mention anything about headlight lense care in contrast to the information on upholstry, paint, trim care etc. Again, planned obsolesnece.(my opinion).
Have a great day!
