Just finish my headlight refurbish
saw a nice clear howto on a english detailingforum
first i wash the light's and clay them,because there where some deep scratches and stonedamage, i started with 350 sanding dry,after that 800dry ,800wet
1500 wet,2500 wet,clean the light's and polish with a wool pad on the drill with plastiX from meguiar's.
its important that you end with 2500 or 3000 grit,scratches from 1500 grit you don't polish away with plastX
I,m very glad with the result and was a little scared to begin at ths job
but take the time to do it ,it's not a thing you do in an hour
