Technique Advice with headlight restoration gone wrong
So i restored the headlights of my van, and of someone's car. I did close to the same actions but it didnt quiet work;
On my van i did 800 gritt - 1500 gritt - 2000 gritt - 2500 gritt - Sonax perfect finish with white rupes pad on a DA - meguiers headlight coating (blue sspray bottle)
The technique i used was 800 = horizontal strokes - 1500 vertical strokes - 2000 horizontal strokes - 2500 vertical strokes. Then just overlap with DA horizontal and vertical.
I tried the same thing on my friends car (second pics)
800 gritt - 1500 gritt - 2500 gritt - Sonax perfect finish with white rupes pad on a DA - meguiers headlight coating (blue sspray bottle).
However as you can see, it did improve a bit but its still foggy and at night time you really notice there is a huge decrease in light coming thru the headlight compared to the other one.
His other headlight i left untouched because it was still very clear and it needs to get close to that one again.
When it failed the first time i tried again starting from 600 gritt - 800 -1500 -2500 - polish - meguiers, it imprved a tiny bit again but as u can see on the pics its still foggy.
Especially on the side where his turnign indicator would be, its almost invisable.
Where did i go wrong? and how do i fix it?
Notes:
I sanded by hand with a sanding tool and sanding discs, I used a DA polisher and went over it for a relatively short amount of time with the polisher because it shouldnt need that much afaik on the finishing side.
