I thought i would pass on my experience in trying to get rid of the small pits on the winshield. these are the tiny little imperfections you can see when driving into the sun.

i recently purchased a Porter Cable 7424 buffer. After i was finnished polishing the car, I decided to see what would happen if i used the buffer on the windshield. I had a new Lake Country buffer pad, The White one, I put it on the puffer and put some Janvil Scratch Remover i had purchased some time ago. I had tried the Janvil before without much success.

I ran the buffer at setting #4. Put some Janvil on the pan and....WOW. It cleaned all the small pits off the windshield. It took about 20 minutes on each side. I ran the buffer on the winshield at 90 deg angles. First a up and down overlapping motion then, Left to right.

As you're buffing keep a small amount of water on the glass to keep it lubricated. An, Keep everything else covered. You will get a lot of splatter all over everything. Cover the rest of the car completly. After you're done just rince the windshield off.

I wish i had taken before and after pictures. It's almost like a new windshield.

For those of you that already have a porter cable 7424 buffer, Give it a try. I was a little worried at first that i would damage the windshield or distort the optics. It didn't.

 

+1 This is one of my tricks I use when detailing cars. people can't believe the results. I use a light compound when i do it.

 

I'll have to try this! I have a bunch of spots that get really bad at night, with street lights or oncoming headlights or such.
