Is it even possible to replace the (not so) clear plastic headlamp housing without incurring the steerable HID price penalty? It would really stink to have to spend $$$ to renew the plastic.
Definitely, acstudios demonstrated it best. Those spider cracks will come out with the appropriate effort if that's what you're referring to as being in the plastic. I didn't get all of them out because it was a first time effort, but the lights look great using the wipe on clear coat after prepping and the residual spider cracks are not easily seen, where before all I needed to do was get close enough.Joseph Upson, as well as some other members, have achieved outstanding results with a few materials and some personal labor.
The added benefit of separating the lens from the rest of the unit for restoral is upon resealing, the condensation issues are corrected. To each their own...
