Do You Wax Your Headlights

Most plastic headlight lenses nowadays are clear-coated (and have been for years). Wax or sealant can't hurt, and IMHO help significantly. I've been sealing/waxing the headlight and taillight lenses on my cars for years -- none have suffered for it; and, my headlight lenses have always been clear. I have a 15 year old BMW (with plastic headlight lenses) that are clear as day; but, I've had to re-finish my son's BMW's (same year as mine) as well as my wife's BMW's (5 years newer) plastic headlight lenses (which were never waxed or sealed) because they were so clouded.

Both of these guys are giving you good advice :biggrin:
 
I will use whatever is applied to the paint at that particular time. (Usually BFWD). Opti-Seal is another good choice. Currently my headlight are wearing Opti-Coat.
 
I eventually always seal them using BFWD because of my recent addiction with BFWD + DA and i'm too lazy to avoid 'em (i can't say enough what a joy using BFWD + DA combination and i even hit the grill too, no stain no streak). I don't know whether there're any benefits or drawbacks of doing so, but currently my rear right tail light had been corrected recently (i believe if there's any factory coating on it, all would no longer remain - i can feel the scratch with my nail and it took good 2++ hours to correct it - it took so long because i didn't sand it and had to wait for the cool down time which for plastics thingy seems to take forever) because my dog was so ambitous in chasing a rat that dancing in my car's roof (my dog also caused moderate deep scratch on rear c panel and rear hatch too! - i really say grace to the lord since i can correct it to perfection by myself and no need to repaint 'em:biggrin:) and till to date there're no sign of early hazing / cloudiness that usually can be found on corrected head / tail lights.:Dancing Dot:

Me, too. If carnauba wax is bad for the headlights, this is news to me. At the moment, my S2K headlights are sealed with BFWD; our CR-V headlights, by 1000p. In the spring I will switch to carnauba wax for the S2K and Ultima Paint Guard Plus for the CR-V.
 
I've never had a headlight on any recent car go yellow on me so I just hit em with some plastic polish. I feel it really does make them look a little clearer.
