BobLevine My 03 Corolla's driver's headlamp was looking very worse for wear. The other side was changed a couple of years ago on warranty for leakage.Tried wet sanding and another brand of plastic polish. Not too bad results but started to weather again.Used Meguiar's Plastx without wet sanding and the headlamp is very close to new appearance. No hard rubbing needed.New headlamp was about $200 + labor. Plastx cost $6.44 + tax at Advance Auto.Product delivers as advertised.
